The media codec renderers have fallback logic in getDecoderInfos
to assume that E-AC3 decoders can handle the 2D version of E-AC3-JOC and
that H264/H265 decoders can handle some base layer of Dolby Vision
content. Both fallbacks are useful if there is no decoder for the
enhanced Dolby formats.
Both fallbacks are not applied during track selection at the moment
because the separate MediaCodecInfo.isCodecSupported method verifies
that the mime type corresponding to format.codecs is the same as the
decoder mime type (which isn't true for the fallback case).
To fix the fallback logic, we can just completely remove this additional
check because it's not needed in the context of this method that is only
called after we already established that the decoder can handle the
format.sampleMimeType.
In addition, we need to map the Dolby Vision profiles to the equivalent
H264/H265 profile to make the codec profile comparison sensible again.
