Enable R8 code shrinking for system_server on Pixel
Opt in to whole-program Java optimizations via R8 for Pixel devices.
This can be explicitly disabled during builds via
`SYSTEM_OPTIMIZE_JAVA=false m`.
Note that this change only enables code shrinking for system_server,
and should not impact stack traces. Additional R8 optimizations
will be enabled after broader improvements to retracing infrastructure.
See go/aperf-system-r8-faq for additional details and guidance. Also
note that R8 shrinking optimizations are implicitly disabled in ENG builds.
Enabling for non-Pixel devices will proceed in stages as we flesh
out infrastructure and validate with test populations.
Results: services.jar (20MB -> 17MB)
Bug: 210510433
Test: m + atest FrameworksServicesTests + manual testing on Raven
