Brings the main fixes and features since 8a8bb2053 to the Play line.
Main's new code keeps the Play gates: bundled PRoot, AddonPack and
ComponentDownloads gates, the SDK guards, PackageInfoCompat and the
accessibility consent check, which now also covers system-key capture.
The accessibility disclosure is rewritten in every locale to describe
the hardware-keyboard keys it keeps in a session. The MaliBridge server
task uses the AGP NDK provider. Review notes are in tools/playstore/POLICY.md.
