Pre-cache filter results

This change adds a cache layer for the return of
shouldFilterApplicationInternal in AppsFilter. This cuts most operations
that rely on app filtering nearly in half by removing a good deal of
branching that used to exist on the critical path for a crosshatch.

Before this CL:
android.os.PackageManagerPerfTest#testGetApplicationInfoWithFiltering:
	getApplicationInfoWithFiltering_mean: 983719
	getApplicationInfoWithFiltering_standardDeviation: 120061
	getApplicationInfoWithFiltering_median: 1061674
	getApplicationInfoWithFiltering_min: 827489
android.multiuser.UserLifecycleTests#createAndStartUser:
	Mean (ms): 4243.10

After this CL:
android.os.PackageManagerPerfTest#testGetApplicationInfoWithFiltering:
	getApplicationInfoWithFiltering_mean: 426340
	getApplicationInfoWithFiltering_standardDeviation: 18861
	getApplicationInfoWithFiltering_median: 427002
	getApplicationInfoWithFiltering_min: 407887
android.multiuser.UserLifecycleTests#createAndStartUser:
	Mean (ms): 3387.25

Note: this is a 2nd attempt at this change that fixes a few from the
previous at ag/11622391. This works with multi-user and updates tests to
ensure this stays true. It also improves peformance when building the
cache by pre-allocating the SparseBooleanArrays to their max sizes.
