Bug 1993083 - Vendor libwebrtc from dc159bf639
Upstream commit: https://webrtc.googlesource.com/src/+/dc159bf6399e52f4a83726fa341f646d9bb041b1
Add file based decoder, which decodes an encoded video file to a Y4M file.
This is a preparation to be able to use FFmpeg and hence, the hardware encoder and decoders.
