Remove unnecessary @TestApi from framework-res

Some resources that were part of the `system` API surface were also
explicitly marked as being part of the `test` API surface too. That is
unnecessary as the `test` API surface extends the `system` API surface
and so implicitly includes everything from it. This change removes the
unnecessary `@TestApi` uses. That removed entries from the
`test-current.txt` file that duplicated entries in the
`system-current.txt` file.

Note: This does not affect `android.permission.MAKE_UID_VISIBLE` which
has both `@TestApi` and `@SystemApi(...MODULE_LIBRARIES)` as the
`module-lib` API surface does not extend the `test` API surface.

Fixes some issues with RESOURCES_FINALIZATION.
