Part of reducing Cobalt's APK size involves removing unused libraries &
classes. One set of source files includes some Variations classes that
fetch Finch seeds, which will not be necessary for Cobalt. Cobalt has
its own YT experiment framework that will not poll the Finch servers.

Test: Build and confirm size reduction in Cobalt.apk

This removes the android crash logging library, since Cobalt
on Android does not use crashpad.

When the application is suspended, StarboardBridge clears its
ActivityHolder()

A timing issue arises if openCobaltService () is called
[here](https://source.corp.google.com/h/lbshell-internal/cobalt_src/+/main:cobalt/android/apk/app/src/main/java/dev/cobalt/coat/StarboardBridge.java;l=673-676;drc=a17da04e52532e5a0480393bc751306db09e97e6;bpv=1;bpt=0)
concurrently, as it may retrieve a null activity from the cleared
holder. This causes subsequent asynchronous communication from the
platform service to fail, because its callback needs a non-null activity
[here](https://source.corp.google.com/h/lbshell-internal/cobalt_src/+/main:cobalt/android/apk/app/src/main/java/dev/cobalt/coat/CobaltService.java;l=100;bpv=1;bpt=0;drc=424d60be6465ceec41b2bcda7b94eaad7539dbb9)
to find the shell's webContents().

To fix this, the activity is now explicitly passed into
H5vccPlatformService and subsequently forwarded as a parameter to
StarboardBridge.openPlatformService(). This ensures the required
activity reference is available directly when needed, bypassing the
potentially null ActivityHolder and preventing the communication
failure.

This adds a build flag for log prefixes. This will make it so all other
log prefixes use "chromium" while Cobalt builds use "cobalt". This is
done with the `IS_COBALT` build flag. Doing this will also make
upstreaming to Chromium simpler in the future.

Bug: b/406576115

1. Add buffer type to DecoderBuffer allocator and
DecoderBuffer::Allocator::Allocate(), so we may using different buffer
pools for different types of buffers in future to reduce fragmentation.
2. Add DecoderBufferAllocatorTest to verify against different allocation
settings of DecoderBufferAllocator.
3. Improve allocation logging in DecoderBufferAllocator with extra
information for using in the above unit tests.
4. Improve ReuseAllocatorBase::PrintAllocations() with extra information
e.g. allocation percentage.
5. Add allocation_extractor.py to extra allocation operations from a
full log to be used in the above unit tests.

Refactor StarboardRenderer with StarboardRendererTraits without
functional changes. This prepares to pass arguments like
|GetCommandBufferStub| in GpuMojoMediaClient, which cannot transfer the
ownership and shared with all StarboardRenderer for decode-to-texture
mode (youtube/cobalt#5158).

Reset |state_| to STATE_FLUSHED after pending flushes. Otherwise, this
will cause a wrong |state_| when StarboardRenderer::StartPlayingFrom.

b/409370497

1. Add a new class DecoderBufferAllocator::Strategy to manage the
allocation strategy, and leave the DecoderBufferAllocator to manage
other details like logging, or destroying the strategy when it's empty.
This allows us to experiment different allocation strategies in future.
2. Clean up the code a bit by removing some unused logic (e.g. the ones
regarding max capacity).
3. Refined DecoderBufferAllocatorTests to allow better comparison of
different configs.
