Enable ThinLTO for hwui
ThinLTO will benefit hwui on both performance and code size.
Now that hwui is with PGO, ThinLTO provides 3.8% performance improvement
on top of it (tested using hwui benchmarks on marlin device).
Enabling ThinLTO also decreases current code size of libhwui.so by 3.2%.
To be mentioned, Thinlto property in bp file will go through all static
libraries that hwui depends on (such as libskia) and enable Thinlto for
them when building hwui.
Test: Build and run benchmarks with ThinLTO enabled.
