Enable PGO for hwui
This patch is trying to apply PGO for hwui. According to some research
on PGO before, we got a 5% to 10% performance improvement with PGO on
hwui and we hope to enable it.
The patch specified a hwui.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 through the PGO collecting script in
the benchmark directory, and it was based on hwuimicro/hwuimacro
benchmark for now.
PGO can be turned of by setting ANDROID_PGO_NO_PROFILE_USE environment
variable.
Test: Build hwui successfully and verified the performance improvement
on device through benchmark.
