Android: inline deprecated BuildInfo methods (/media/audio)

No change to logic. This inlines BuildInfo.isAtLeast{Q,R} and
BuildInfo.targetsAtLeast{Q,R} (and their C++ equivalents) in
/media/audio.

The methods themselves will be removed in a follow-up CL once all call
sites have been removed.

This CL was uploaded by git cl split.
