-----------
[MSE] GPUConnection::sendSync should only ever be performed on the main thread
https://bugs.webkit.org/show_bug.cgi?id=269459
rdar://123005739
Reviewed by Youenn Fablet.
We run the sendSync operation through the main thread, as running them through
the MediaSourceRemote WorkQueue could trigger an assert in debug build or out
of order events otherwise.
The modified methods are already called on the main thread so we have no risk in
introducing a dead lock.
Covered by existing tests. No change of behaviour.
