Subject: [PATCH] Make VMCompilationPerformance an aggregated profile with
 default

The VMCompilationPerformance profile is used to run Isolated Compilation
in a Protected VM, normally during the device idle, where relevant
APEXes are staged.

The original VMCompilationPerformance introduced in aosp/2060891 does
not have any specific definition and requires vendors to customize it.
This change re-defines it as an aggregated profile with a default set of
existing profiles, so that performance can be reasonable by default.

This profile may be renamed to a more generic name later, e.g.
"SCHED_SP_COMPUTE".

Bug: 231437770
Test: Run `composd_cmd test-compile` on a local device.
      Before: 1m50s +/- 10s (with whatever that's default)
      After: 1m25s +/- 5s
