Update libwebrtc up to M120

https://bugs.webkit.org/show_bug.cgi?id=265987
rdar://problem/119302684

Reviewed by Jean-Yves Avenard.

Update libwebrtc while retaining specific changes, in particular the ones related to HEVC.
We stick to the newly deprecated DSN resolver API and will do the switch in https://bugs.webkit.org/show_bug.cgi?id=265791.
We introduce a new libwebrtc.debug.exp since some symbols are only enabled when RTC_DHECK is on.

Covered by existing tests.
