Remove unused compile command --compile-layouts

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.
