[MSE] Add per-track signalling between SourceBuffer and SourceBufferPrivate.
https://bugs.webkit.org/show_bug.cgi?id=125899

Reviewed by Eric Carlson.

To accommodate the future addition of audio support to MSE in the Mac
port, add the concept of trackIDs to the communication between
SourceBuffer and SourceBufferPrivate.

The following virtual methods  now take a trackID parameter:
* platform/graphics/SourceBufferPrivate.h:
(WebCore::SourceBufferPrivate::isReadyForMoreSamples):
(WebCore::SourceBufferPrivate::stopAskingForMoreSamples):
(WebCore::SourceBufferPrivate::notifyClientWhenReadyForMoreSamples):
* platform/graphics/SourceBufferPrivateClient.h:
(WebCore::SourceBufferPrivateClient::sourceBufferPrivateDidBecomeReadyForMoreSamples):

Update overridden methods in subclasses:
* Modules/mediasource/SourceBuffer.cpp:
(WebCore::SourceBuffer::sourceBufferPrivateDidBecomeReadyForMoreSamples):
* Modules/mediasource/SourceBuffer.h:
* platform/graphics/avfoundation/objc/SourceBufferPrivateAVFObjC.h:
* platform/graphics/avfoundation/objc/SourceBufferPrivateAVFObjC.mm:
(WebCore::SourceBufferPrivateAVFObjC::trackDidChangeEnabled):
(WebCore::SourceBufferPrivateAVFObjC::isReadyForMoreSamples):
* platform/mock/mediasource/MockSourceBufferPrivate.h:

Change the logic in provideMediaData to update a single TrackBuffer
rather than iterating over all of them:
* Modules/mediasource/SourceBuffer.cpp:
(WebCore::SourceBuffer::sourceBufferPrivateSeekToTime):
(WebCore::SourceBuffer::appendBufferTimerFired):
(WebCore::SourceBuffer::provideMediaData):
