Allow multiple URL.createObjectURL invocations for MediaSource

Currently calling URL.createObjectURL for a MediaSource more than once
causes an assert/crash due to MediaSource::m_isAddedToRegistry flag
being already set. But since calling createObjectURL is actually a
valid thing to do and should just generate new unique URLs, let's
replace the m_isAddedToRegistry flag with a counter.
