Remove switch kEnableWebRtcHWH264Encoding

switches::kEnableWebRtcHWH264Encoding was added for
extensions and can be used before SW fallback is in place.
Now it's time to remove it since SW fallback is already
ready for all desktop platforms.
BTW: Another reason is after cl
https://codereview.chromium.org/2358683002/
has landed, the checking to switches::kDisableWebRtcHWEncoding
is having the same effect.
