Actually use the hdr mapper for AV1 in GetHdrProfileLevelMapper

It's defined but not returned by GetHdrProfileLevelMapper, so
soft AV1 doesn't report HDR support.

bug: 138314480
test:

atest android.media.cts.DecoderTest#testAV1HdrStaticMetadata
atest android.media.cts.MediaMetadataRetrieverTest#testThumbnailAV1Hdr

Test should pass, AND test shouldn't be skipped.
For MediaMetadataRetrieverTest#testThumbnailAV1Hdr, enable output
file dump and there should be output file dumped.
