Having soong generate a list of makefiles for mk2rbc
to look through is much faster than having mk2rbc search
itself. Profiling the readLinesFromeFile() function that
reads the list of makefiles shows it takes on the order
of 200 microseconds, much faster than the ~5 seconds
it takes for mk2rbc to search the tree itself.
This CL also allows include statements that are prefixed
with a variable. The concern with this was that there
would be a lot of load statemnts emitted for generic
include statements, causing the generated code to look
ugly, and converting and loading all those files could
cause performance issues. On the performance issues
front, there's already a check that it doesn't result
in over 150 potentially included files. We can lower
that number if necessary, but it's probably good for now.
On the generated code front, while it's true that it's
ugly, it's better to have working but ugly generated
code than refusing to generate anything working at all.
To ensure the soong finder step isn't slowed down due
to having to find a bunch of new makefiles, I profiled
the combination of newSourceFinder and FindSources in main.go:

The expfetcher binary (added in
https://critique.corp.google.com/cl/424076941), can fetch experiments
configuration from CDPush and load them into Soong as part of its
startup. If the binary exists, then we use it to fetch experiments
config and put them in the out directory so that those env variables can
be loaded by Soong during startup and inturn control whether RBE should
be enabled or not.

When the environment variable config file is loaded after config object
is initialized, we end up loading the USE_RBE variable in the config
file after the code to start reproxy process is run. This causes a
problem when USE_RBE variable itself is set in the config files. To
avoid this, I've moved the config file loading code to be within the
config package, this makes the main.go file cleaner too.
Test:
Ran a build with USE_RBE:true set in the config json file. The build
fails without this change and succeeds with this change.

Reproxy should be respecting the -j value set by the user and not be
doing excessive local executions assuming the whole machine is available
to it. The local_resource_fraction flag is a way to ensure reproxy
consumes CPU only upto the -j value specified by the user.

was set to 0.14 on a 72-core workstation.

This behavior is enabled by setting the environment variable
SOONG_UNBUFFERED_OUTPUT=1 .
This is not the default behavior because only one process can be running
in the console pool and this would thus result in a loss of parallelism
if multiple soong_build invocations are needed.
Changing the value of this environment variable does not result in a
rebuild, since it does not affect the build outputs.

It's built explicitly by Microfactory but is under out/ and as such, it
would be normally flagged as a file in out/ that doesn't have a
generating rule.
Previously, a no-op rule was added to the Ninja file to prevent this
from happening, but there is no good reason to have two mechanisms to
exempt files under out/ from that check.

Move cc module installation rules into Soong by overriding
InstallBypassMake. Update the locations that find host tools
to look in the Make installation directory instead of the Soong
installation directory, which will no longer be used.
The methods that find host tools are also used on go binaries,
so update the config methods that tell Blueprint where to install
go binaries to the Make installation directory too.

It's better not to have state hidden in dotfiles (or rather,
dotdirectories) if we can help.
It's questionable whether the "linux-x86" path segment makes sense since
soong_build only ever runs on one operating system, but I didn't want to
rock the boat now.
Drive-by fixed some quoting fixes in rbc-run. Notably, I didn't wrap
`$@` into double quotes because I don't know whether the lack of double
quotes was intended or not.
Also drive-by fixed the fact that "out/soong" was added twice to the
directory name of bpglob. This turned out not to be a problem because
bpglob doesn't need to be explicitly built: if it's needed, it's
declared as an input of the glob files so it'll be built automatically
(at the cost of the first "null build" not actually being a null build)

ToolDir is going to become unstable when switching between KatiEnabled
and Soong-only builds while the duplication between out/soong/host and
out/host is resolved. bpglob gets executed very early during bootstrap,
before the primary builder has run to update the paths to match the
current configuration. Move it into SoongOutDir() so that its path
is more stable.
Moving bpglob causes incremental build issues, so add a bootstrapEpoch
constant that can be changed when making incompatible changes and will
wipe bootstrap intermediates.

This was reverted unnecessarily along with the change that actually
broke the build.
Previously, the sdk snapshot was assumed to be generated for the
current build system. This change adds support for the
SOONG_SDK_SNAPSHOT_TARGET_BUILD_RELEASE environment variable which can
be used to select the target build release in which the generated
snapshot will be used.
At the moment this will only affect the properties that are output but
if/when it becomes necessary it can also be used to control more
aspects of the snapshots such as supported member types or even
members.
This change does not modify any properties that are build release
specific. That will come in following changes. However, it does add a
test that targets build release S which defines a baseline for
properties that will be affected in following changes. That baseline
makes it easier to see the effect of those follow up changes.

`m product-graph` runs a "non-full" build, which skips
some steps to improve performance. One of the steps
it skips is making a .installable_files file. Soong
reads this file and removes any files that were removed
from the list in this file. It errored out if the file
didn't exist. Make soong less strict about the presence
of this file, because if it doesn't exist, there shouldn't
be any installed files to remove either.

This makes soong_ui the only place where soong_build is invoked, thus
greatly simplifying the conceptual model of the build.
It comes with the slight limitation that now soong_docs (and queryview
and the JSON module graph) are not Make targets anymore, but I suppose
that's an acceptable loss.
The only place where someone depended on soong_docs from a Makefile is
removed in a separate change.

This includes the JSON graph generator and bp2build.
Before:
GENERATE_BAZEL_FILES=1 m nothing
GENERATE_JSON_MODULE_GRAPH=1 m nothing
Now:
m json-module-graph
m bp2build
They can now also be combined with other targets or each other.
The longer-term goal is to run "m queryview" and "m soong_docs" using
the same infrastructure. There are two alternate approaches:
1. Call soong_build from within the main Ninja invocation. This requires
two sequential soong_build invocations and is thus slower.
2. Do everything requested in the same soong_build invocation. This
would be faster, but one AFAIU can't tell Ninja that multiple possible
actions can build the same output so that doesn't work.
(1) is somewhat more desirable because soong_docs seems to be built
from build/make/core/main.mk ; I assume that that can be worked around
although I haven't checked where the output of "m soong_docs" goes.

Before, we piggybacked on the implementation of regular soong_build and
wrote a fake build.ninja file to satisfy Ninja.
Now, instead, the JSON module graph is a a separate action in the Ninja

and forth between generating the JSON file and regular Soong without
loss of incrementality.
