Bug 1909234 - Vendor libwebrtc from e0b28a6a81

Upstream commit: https://webrtc.googlesource.com/src/+/e0b28a6a81a989c1f5c89e30fcd247870047390d
    [Merge 127] Reset the speech encoder when creating a comfort noise encoder.

    This is to make sure that the two encoders are "in sync" (the CNG
    encoder can be created from an existing speech encoder).

    This is a speculative fix for a crash in the CNG encoder where a packet
    is unexpectedly emitted from the speech encoder.

    (cherry picked from commit 0fd67312ea078b3b997306d56284b85492b37650)
