Generate a baseline profile for release builds

Browse Source 
Cold starts ran unoptimised: no profileinstaller dependency and no
profile in the bundle, so ART interpreted Compose on first launch
(class verification measured at 128 bytecodes/s in an emulator ANR).

Add the androidx.baselineprofile producer module with an AOSP managed
device, a generator covering startup plus the four detail tabs, and
commit the generated baseline and startup profiles.
