This feature is obsolete.
This makes a large number of codepaths "dead code" (such as
module-specific implementations of ApiBp2build functionality). These
will be deleted in a followup CL.

These tests cannot be run with b since it uses functions that should not be
used outside tests, and it enforces this by looking at os.Args. Since
the pattern (`-test`) is missing in os.Args, these tests panic in b.
A module can be a dep of soong_build via two mechanisms
1. Listed in deps explicitly
2. Via plugin_for to create a reverse dep
This CL denylists (1) explicitly. e.g. soong-android. Another option
would have been to denylist by using Deps() of soong-build, but that
would denylist `golang-protobuf-proto` as well
This CL denylists (2) programmatically.
Note that this CL only denylists creation of the `go_test` target. We
will still create `go_binary` and `go_library` for soong since there
might be tools that depend on soong.
e.g.
```
--> depends on
dexpreot_gen --> soong-dexpreopt --> soong-android (test failure)
```
(The above example means that we might need to convert _some_ of soong
after all, but we can refactor the common bits to common utils. Keeping
this out of scope for now).
Test: b test //build/soong/... //system/tools/...
too)

For go modules with non-empty testSrcs, we will create an additional
go_test target. To build a standalone test executable, we need to
include the source files in the compilation unit. This will be done
using the `embed` attribute
1. For tests of go_library, this is straightforward. It will embed the
go_library and "inherit" its .go files and deps
2. For tetss of go_binary, we need to create an additional go_source
target since go_binary cannot be embedded inside a go_test
Using `b test` for these tests revealed that certain tests are not
hermitic and rely on `testdata` files checked into the tree. This CL
introduces an allowlist to skip generating go_test targets for them.

This module type does not implement android.Module, and therefore we
cannot write a conventional bp2build converter for this module type.
Instead this has been special-cased inside bp2build/build_conversion.go.
There is one major deviation between Soong and Bazel's
go_binary/go_library. Soong
collects the deps in the transitve closure and puts them on compile/link
paths. Bazel OTOH, requires the direct imports to be listed in deps of the binary
explicitly (AFAIK). Since bp2build cannot determine the list of direct
imports from the list of transitive deps, put all the transitive deps in
`deps`

This module type does not implement android.Module, and therefore we
cannot write a conventional bp2build converter for this module type.
Instead this has been special-cased inside bp2build/build_conversion.go.
Because of the above, we also do not have access to useful functions
available in the ctx object of ConvertWithBp2build. This includes
1. Finding the package (directory) of a dep. This requires getting a
handle of the underlying module from its name (string). To solve, we
do a pre-visit to collect this information. This did not increase the
wall time. On my machine, `m bp2build --skip-soong-tests` takes ~14s
before and after this CL
2. Converting srcs to labels. This requires glob and package boundary
resolution. This CL introduces a partial implementation for this
function. (glob patterns are not used in go tools)
For (1), I considered creating a `ModuleFromName` on
`blueprint.Context` instead of a pre-run, but this increased the time to ~27s.

This also changes the expectation of ConvertWithBp2build. Each
implementation must either create one or more Bazel target modules, or
mark the module as unconvertible (with a specific reason).
Manually verified no runtime hit in AOSP
In AOSP, the metrics file size increases from 252K to 1.6M
This changes some effective module counts in bp2build metrics:
- Removes "package" modules from the module count list in
metrics, as these will not be converted like regular modules.
- Counts Handcrafted modules as being "unconverted", as bp2build is not
responsible for them.

The use case for this is creating config_setting(s) specific to an apex

only a handful of such config_setting(s), but determining that list
requires iterating the build graph.

The expected use case for this is to create aliases for stub libraries
in the @api_surfaces repository in build/bazel/api_surfaces.
This restricts the scope to just aliases. If we have a use case for
generating actual Bazel targets in another directory, a workaround could
be to generate the targets in the current directory (via
CreateBazelTargetModule) and aliases to it in the other directory

The generated Bazel workspace will only contain api specific targets.
This is feasible since these targets do not have any cross dependencies
with the targets in the bp2build workspace
The advantages of a new mode are
1. Does not pollute bp2build workspace with api targets
2. Does not block api targets with the current allowlist conversion
mechansims in bp2build
(In the future we might want to combine these two workspaces)
A Soong module type will generate a Bazel target if it implements
ApiProvider interface

* We are interested mostly in the conversion the `default_applicable_licenses`
attribute, as `default_visibility` cannot be handled until every module's
`visibility` is handled.
* Several referenced license modules had to be manually enabled for
conversion, and likewise a few trivial Android.bp containing only
package and license modules.
* As Bazel allows only a single `package` rule, the package rules in a
manually converted BUILD.bazel files were removed (in
external/protobuf and prebuilts/clang/host/linux-x86 trees).
* The converted package rule is emitted before the `load` statements per
Bazel documentation.

variable usage.
There's bug a in the current soong_config_variable handling
implementation where a soong_config_variable sets conditions_default
value for an attr, and a non-conditions_default value for another attr.
This results in the former attr not properly setting the zero value for
the non-conditions_default select key, resulting in the pretty printer
omitting the attribute totally.
The current implementation in this CL ensures that the zero value is set
whenever this happens at the module level. This is seen in
library_linking_strategy_cc_defaults (see comments in code, and the new
tests)

For structs that are embedded, Blueprint does not nest under the
embedded name, flattening them into the original struct for blueprint
files (e.g.
9fd2ed93df:proptools/unpack_test.go;l=402-431;drc=3adb2409648d6f8b25354ac47f083dae87731f10).
We should do the same for bp2build.
This will also allow us to embed structs for bp2build conversion
allowing more reuse.

A performance improvement for bp2build as Blueprint/Soong no longer have
the overhead of additional modules. The creation of these modules
results in:
* traversal of additional modules for each subsequent mutator
* synchronization over a go channel to collect newly created modules:
https://cs.android.com/android/platform/superproject/+/master:build/blueprint/context.go;l=2594,2600;drc=1602226f23181b8c3fbfcaf3358f0297e839d7d3
We avoid both of these by storing the information directly in the
underlying module.
Also as a fringe benefit, removes some necessary boilerplate for
conversion.
For benchmarks, reduces runtime ~1% for 1% converted, ~24% for 100%
converted. See more: go/benchmarks-for-https:-r.android.com-1792714
