Context
- from-text android.jar files are built using Metalava, and these can be
utilized in `decodeSdkDep` so that any modules that depends on APIs
can be compiled using from-text android.jars
- This change removes dependency on source java files when compiling
stub android.jar files
Implementation
- Modify java_api_library module to create system modules using the
generated android.jar
- Replace modules in decodeSdkDep to link against java_api_library
modules
- Add --build-from-text-stub flag to hide the feature behind a flag

Previously, symlink forest generation involved removing the entire
symlink forest and recreating it from scratch. With this change,
a) symlinks which need not change are untouched,
b) symlinks pointing to the wrong location are fixed, and
c) symlinks which should no longer exist are removed.
On AOSP on my local machine, this reduces the symlink forest generation
step from 2.5s to 1.1s clean, and 0.6s when a single file is added to
a source directory.

Test: m bp2build, touch `fakefile` under the forest, remove a file

Define a structure android.CmdArgs and keep all soong_build command line

The synthetic soong_injection workspace is shared between api_bp2build
(used in API export) and bp2build (used in API domain analysis which
runs mixed builds by default). The former creates them in ReadOnly mode,
but the latter creates them in ReadWrite mode (to allow users to
edit/experiment). To prevent errors in the end-to-end builds in
multittree, make api_bp2build create these files in ReadWrite mode as
well.

Background: toolchain/llvm_android/test_compiler.py generates clang-dev, a directory
symlink pointing to out/install/linux-x86/clang-dev, which itself
contains a BUILD file. This BUILD file should be excluded from the
symlink forest because it's not an allowlisted BUILD file.
Problem: However, our current symlink forest logic and finder logic doesn't
handle this situation. It's not in bazel.list:
```
$ less out/.module_paths/bazel.list | grep prebuilts/clang
prebuilts/clang/host/linux-x86/BUILD.bazel
prebuilts/clang/host/linux-x86/cc_toolchain_config.bzl

prebuilts/clang/host/linux-x86/clang-r468909b/BUILD.bazel
prebuilts/clang/host/linux-x86/clang-r475365/BUILD.bazel
```
The symlink forest logic uses this bazel.list file and matches it
against the keepExistingBuildFile list to exclude BUILD files from the
symlink forest. Since clang-dev/BUILD.bazel is not in bazel.list, it's
symlinked into the forest.
All of these gymnastics could be avoided if we added custom BUILD file
name support to Bazel, and only symlinked (e.g.) Android.bazel and
ignored all other BUILD files in the tree. It would be very clear which
checked-in BUILD files we want to use in the symlink forest.
I think we should pursue custom BUILD file names instead of adding more
complexities, to say, the finder logic, to support such a use case. It's
also why I decided to add this hardcoded exclusion to keep the
workaround simple.

BUILD/bzl files, and we create symlinks for that subsset in

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.

Previously, the NewTextContext created a context that always called
NewNameResolver with a export filter that always returned true.
This change fixes that by:
1. Changing NewNameResolver to take a Config parameter instead of a
filter parameter and pushing the code to create the filter from the
Config from newNameResolver() in cmd/soong_build/main.go into the
NewNameResolver function.
2. Extracting a newTestContextForFixture that does not create a
NameResolver or set it on the context. That avoids creating a
NameResolver before the test has prepared the config.
3. Modify the fixture to create and set the NameResolver in the Context
after the config has been prepared by the test.
4. Added test to verify that it all works.

Each build mode has to provide an output file, which also has a
corresponding dependency file (<output file>.d). Previously, some of
the build mode functions returned that file, others just returned and
relied on the doChosenActivity() method to return the file.
That was confusing as the same file name was referenced from two
separate places. This change makes all the build mode functions return
their output file explicitly and the doChosenActivity()just returns
what it receives. It also moves the writeDepsFile call to adjacent to
the return.

Previously, the Context object created in the main() method was
initialized (ctx.Register()) for the main soong build. Build modes
that did not want that build modes that did not want that (symlink,
bp2build, apiBp2build) had to create their own context, or in the
case of runSymlinkForestCreation its own EventHandler. That was
very confusing.
This change avoids that by simply pushing the call to ctx.Register()
into the build modes that require it and that allows the other build
modes to use the main context and its EventHandler.
One point to note is that to ensure the exact same initialization as
before the runApiBp2build has to explicitly call the following:
ctx.SetAllowMissingDependencies(false)
That is because the main context could have that set to true.

Previously, running `m nothing` would write the soong_build_metrics.pb
file 3 times:
1. For bp2build - it contains a single `soong_build` event as the rest
is written to the `bp2build_metrics.pb` file.
2. For Bazel symlink forrest - it too contains a single `soong_build`
event as the rest is appended to the `bp2build_metrics.pb` file.
3. For soong_build proper (including mixed builds) - it contains useful
information.
This change avoids that by pushing the code to write the
soong_build_metrics.pb file from the top level where it applies to all
build modes into the build mode specific function that needs it.

Retrieving an environment var through Config.Getenv() automatically
adds it to a soong.environment.used* file along with its current value.
Changes to its current value will trigger a rebuild of the appropriate
target. The LOG_DIR is a sub directory of DIST_DIR and on build servers
DIST_DIR encodes the build number making it unique every time. So,
using Config.Getenv("LOG_DIR") will mean the CI builds will never
re-use the previous output.
Previously, bp2build and symlink forrest both added LOG_DIR to their
respective soong.environment.used* file. This change avoids that by
passing through the value from the main() function which retrieves it
using availableEnv["LOG_DIR"] which avoids it being added to that
file.

Previously, writeDepFile was passed a copy of the main EventHandler to
which it then added an event. Adding an event requires appending
information to slices in the EventHandler structure. As the slices are
a copy the addition only affects the copy and are not present in the
EventHandler which is written out as part of the metrics.
This change fixes that by passing a pointer to an EventHandler into
writeDepFile. For consistency it also replaces a few other uses of
EventHandler with *EventHandler instead.
