Enable PA_KILL during PA_KILL_BOOST

sync with ag/28274083.

Currently, we enable PA_KILL always on camera launch. This CL puts this
feature behind a power boost profile which can only be triggered from
camera hal and is controlled by a mendel flag.

Bug: 356005553
Test: 1. adb logcat
      2. gca_smoke.py test pass
Flag: EXEMPT resource only update
