Prepare for @RequiresApi class retention

The android framework has android.annotation.RequiresApi, which is a
copy of androidx.annotation.RequiresApi. However it was added with
source retention instead of class retention like androidx's version
has. This causes it to be missed if you compiled a library and then
used that library to compile something else, that library's public
methods won't have @RequiresApi on them when using that library's
compiled jar file.

To make @RequiresApi have class retention, we need to baseline the
NewApi issues that it would cause. These baselines also require
us to disable strict_updatability_linting in some places.
