Add BRD tests to verify exceptions

Test: This

I0bf8c4c72cc118d2799a59e8eb6c2cede546fceb added @NonNull annotations to
BitmapRegionDecoder#newInstance, and
Ifd9e9abe3f2c89f724a0b918d99ec4e9db65ad56 fixes one of them. Verify that
various forms of bad input behave as expected, whether that's by
throwing an Exception or returning null.
