Log Message
Make SharedBuffer inherit from ThreadSafeRefCounted
https://bugs.webkit.org/show_bug.cgi?id=230662
rdar://83419269
Source/WebCore:
The SourceBufferPrivateAVFObjC uses dispatch_async that takes an objective-C class.
This copies its argument rather than move it and we end up with the SharedBuffer
captured in the lambda to have its ref count be > 1.
The easiest workaround is to make SharedBuffer use thread-safe refcount.
Of course, this doesn't make a SharedBuffer a thread-safe class, but it allows
to safely move it between threads.
Already covered by existing tests.
