AOSP: Use '-Os' rather than '-Oz'

Cuttlefish recently hit a clang compiler issue related to -Oz:
  b/200617543

This is fixed by either disabling optimizations for ScopedExit or using
-Os.

This CL will switch ANGLE to using -Os.

When building CF in AOSP, the binary size is reduced with -Os vs -Oz:
  -Oz: 16,383,489 bytes
  -Os: 16,152,509 bytes
