Revert "Add 4K+ portrait resolutions for the H264 and VP9 DXVA decoders."

This reverts commit 2d7795fe.

Reason for revert: DXVA resolution checks are for explicit w:h pairs, adding portrait prevents landscape from working... This needs to be reworked to return multiple supported profiles.

Original change's description:
> Add 4K+ portrait resolutions for the H264 and VP9 DXVA decoders.
> 
> H264 is most affected since VP9 gets 4K portrait support by virtue
> of supporting 8K decoding. This cl also adds 8K portrait mode
> support for VP9.
> 
> BUG=806568
> TEST=manually verified video in bug gets GpuVideoDecoder.
