      Remove unused compile command --compile-layouts · 51fdab00
      Jackal Guo authored 
      The 'pm compile --compile-layouts' is deprecated, and it leaves the
possibility that malicious apps could do a side channel attack. Re-
move related entry to mitigate this.

Bug: 241233589
Test: atest dex-builder-test
Test: manually using the PoC in the buganizer to ensure the symptom
      no longer exists.

      Preload font before TypefaceSerializationPerfTest. · 23f1be2d
      Kohsuke Yatoh authored 
      This CL disables lazy font loading by preloading font in setUp(),
in order to stabilize testSerializeFontMap() results.

In testSerializeFontMap(), the first serializeFontMap() takes 20x time
due to lazy font loading (first call 40ms / avg 2ms on oriole).
This makes test results unstable by reducing the number of iterations.

ManualBenchmarkState calculates the number of iterations
('mMaxIterations') as follows:
    mMaxIterations = (int) (mTargetTestDurationNs / (warmupDuration / iterations));
where 'iterations' is the number of iterations done in warmup stage.
If the first iteration in warmup stage takes unusually long,
'iterations' becomes small and mMaxIterations will be smaller as well.
