Mirko Bonadei 611f21d0d4 Revert "Add HEVC support for h264_packet_buffer."
This reverts commit a2655449ee.

Reason for revert: H265 tests must be hidden behind RTC_ENABLE_H265.

Original change's description:
> Add HEVC support for h264_packet_buffer.
>
> Renamed to h26x_packet_buffer as it also supports HEVC now. For HEVC,
> start code is added by depacktizer, and remote endpoint must send
> sequence and picture information in-band.
