Revert of Add H264 profile to webrtc::VideoCodecH264 and webrtc::VideoPayload (patchset #1 id:40001 of https://codereview.webrtc.org/2525693003/ )

Reason for revert:
The CL doesn't actually set profile information in VideoPayload.

Original issue's description:
> Add H264 profile to webrtc::VideoCodecH264 and webrtc::VideoPayload
>
> It's necessary to check H264 profile information as well as payload name
> in PayloadIsCompatible in RTPPayloadRegistry.
