This patch is to turn on PGO for skia on Android, which will provide a
performance improvement of 7.6% for hwui when applied PGO for both.
The patch specified a skia.profdata file, which locates in internal
google_data/pgo_profile directory, to work as the profile to feed PGO.
This profdata can be re-collected with PGO build system support.
PGO can be turned off by setting ANDROID_PGO_NO_PROFILE_USE environment
variable or set variable to false.
Test: Build skia successfully and verified the performance improvement
on device through benchmark.
