Scaffolding for AnnotatedUserHandles testing.

This provides (test-only) capacities to inject different
UserHandle values than the ones we'd normally determine, so that
we can test under artificially-constructed scenarios just by
injecting the appropriate fake AnnotatedUserHandles value.

Test: `atest AnnotatedUserHandlesTest` (& presubmits/etc)
