Summary [MediaRecorder/WebM] Inefficient memory usage driven by libwebm's mkvmuxer

Reported 2024-10-13 16:00:33 PDT
The mkvmuxer writes data on average one or two bytes at a time and we append those bytes for a FragmentedSharedBuffer ; profiler shows that a lot of time is spent allocating the Vector that will contain this data and highly fragmented memory usage. We should pack it up in block instead.
