hiddenapi: Prevent libraries for Q/R from include S+ flags.
The Q and R runtimes can handle Q/R flags but not S flags. So, this
change verifies that any library that can run on Q/R
(min_sdk_version <= R) by adding --max-hiddenapi-level=max-target-r
to the "hiddenapi encode" command. That will cause a failure if any
S+ flags are found in the flags to encode.
Bug: 172453495
Test: m droid && launch_cvd
Cherry pick changes in https://r.android.com/q/topic:max-target-s
Add @UnsupportedAppUsage maxTargetSdk=S in classes in framework-permission (for r/q)
and framework-permission-s (nominally for S+). I had to incresed the min_sdk_version
in the latter to 31 (S) as it was still set at 30 (R).
