chore: cherry-pick 38781b86f0 from chromium

MediaRecorder: tolerate non-GMB NV12 frames for H264.

The VPX video track recorders were updated to tolerate non-GMB NV12
input in crrev/c/2425748, but the H264 encoder was left neglected,
which hurts Mac users that have disabled hardware acceleration. This
change adds that support to it.
