Attachment: Bug 1907378 - do not always prefer H.264 on Android for WebRTC. r=dbaker

In early Android days, H.264 is the best choice of video codec
for WebRTC because it's available on most devices. This is no
long the case.

The patch only stops strongly preferring H.264 on Android, which overrides user preference. The default codec list should be further improved according to codec support on device capabilities such as HW acceleration. Filed bug 1909557 to follow up.
