add srcover_bgra_8888
Chrome generally uses BGRA buffers, so srcover_rgba_8888 isn't really
doing them any good. Probably a good idea to cover both kN32 options
any time we specialize like this?
There's one small diff, so I've lazily guarded this by
SK_LEGACY_LOWP_STAGES, which I want to rebaseline today anyway.
