This feature is toggled on with USE_PERSISTENT_BAZEL, which is off by
default. Those that opt-in will have a bazel server running between
builds (with a 3hr default TTL) which will greatly improve analysis on
subsequent builds. (As Bazel maintains a cache of analysis results).

This contains the environment variables set by soong_ui during the ninja
execution. This file will be unused in single-tree builds, but will be
useful for multi-tree. The orchestrator will use this file to set the
correct environment for each inner tree build in the combined ninja
execution.

2. Set
```

bar and foo will be included if and only if <val> is set

Add a new argument in soong_ui that will be used to gate this behavior.
This approach is expected to solve incrementality issues in multi-tree.
As part of soong's bootstrap process, all source dirs are added to deps
of out/soong/build.ninja (via globs). Since multitree_build writes to the
"source" api_surfaces directory, it changes its mtime and causes a
recompilation of out/soong/build.ninja in the subsequent invocation.
Test: TH (for single-tree)
Test: Inspected ninja files (for multi-tree)

This ensures that soong_ui is successful in setting up its own nsjail in
workflows that externally make the source tree ReadOnly (e.g. a nested
nsjail in multitree).

The following environment variables are no longer used when generating
sdk snapshots:
* SOONG_SDK_SNAPSHOT_PREFER - we can control the modules that are
preferred at build time now.
* SOONG_SDK_SNAPSHOT_USE_SOURCE_CONFIG_VAR - this is done as a
post-processing step by the mainline_module_sdks.sh script to avoid
having to regenerate the ninja files for every module.
* SOONG_SDK_SNAPSHOT_VERSION - support for this was removed a long time
ago but was still referenced from dumpvars.go.

This will make it easy to change a "false" boolean to "true" to push
`--bazel-mode` by default for all users.
Users may disable bazel-by-default with BUILD_BROKEN_DISABLE_BAZEL, and
bazel is disabled by default on Darwin hosts (due to lack of test
coverage).

Test: Prior to thi CL bp2build.symlink_forest event was missing in bp2build_metrics.pb after a clean mixed build
Change-Id: I53bfc4114a383c0d1f9c4c7945e7d4c69bc50b0c
This helps with incrementality a lot: the symlink forest must depend on
almost every directory in the source tree so that if a new file is added
or removed from *anywhere*, it is regenerated.
Previously, we couldn't do this without invoking bp2build, which is
quite wasteful because bp2build takes way more time than the symlink
forest creation, even though we do the latter in a very suboptimal way
at the moment.
This means that if a source file is added or removed (which does not
affect globs), we don't pay the cost of bp2build anymore.
Also refactored symlink_forest.go on the side. Too much state was being
passed around in arguments.
This change reimplements aosp/2263423 ; the semantics of not touching an
output file is the exact same as order-only inputs and the latter is a
bit fewer lines of code.
Test: Presubmits.
