Reland "Android: Query encoder for supported pixel formats"

This is a reland of 0bd5cafd
The original implementation would incorrectly try to use other
pixel formats besides COLOR_FORMAT_YUV420_SEMIPLANAR and
COLOR_FORMAT_YUV420_PLANAR

Original change's description:
> Test H264VideoEncodeAndValidate would fail on devices that don't
> support COLOR_FORMAT_YUV420_SEMIPLANAR. This make it so the test
> queries the encoder, and then take the color format from the
> returned set.
