Bug 1828517 (MOZ) - Simplify RTCStatsTimestampMaker conversions with a new RTCStatsTimestamp class. r=webrtc-reviewers,dbaker

This adds a new helper class that has the same conversion state as
RTCStatsTimestampMaker, for conversions on any thread.
It has From* and To* methods for all the time bases we care about, and stores
its time internally in mozilla::TimeStamp.

This avoids having to implement a conversion method for every permutation of
time base pairs in RTCStatsTimestampMaker.

Bug 1828517 (MOZ) - Improve rtp packet delivery through MediaPipeline and conduits. r=webrtc-reviewers,dbaker

With earlier fixes to upstream's PacketReceiver::DeliverPacket, received rtp
packets were parsed twice:
- In MediaPipeline, with the proper extension map in order to extract the header
  for filtering.
- In conduits, with no extension map.

The conduits would therefore not parse any rtp header extensions, leading to
problems later on as data from the extensions would not get exposed to
libwebrtc or js.

This patch removes the rtp packet parsing in the conduits and moves any setting
of metadata over to MediaPipeline so there is a single point responsible for
parsing rtp packets. The packet is then transferred verbatim via the conduits to
libwebrtc.

Upstream removed:
ReceiveStreamInterface::transport_cc
ReceiveStreamInterface::SetTransportCc

While working on this, I ran into trouble because include chains starting in
generated DOM cpp code were reaching deep down into libwebrtc, which expects
certain preprocessor defines to be set. Our cpp code sets these defines, but
the generated DOM cpp code does not (and should not). So, I've reworked the
includes and added forward declarations to avoid this problem.

Also, added a TODO about using this new API over in bug 1825877.

Bug 1825360 - Remove the NS_DISPATCH_SYNC flag, r=necko-reviewers,geckoview-reviewers,media-playback-reviewers,karlt,jesup,m_kato,emilio

This flag is not supported by most event targets and can have unexpected
side effects (namely spinning a nested event loop). All consumers have
been replaced with a new function which is more explicit about this side
effect.

This method always returned GetMainThreadSerialEventTarget(). This patch
switches all callers over to use that method instead.

We can't easily switch all calls to be calls to NS_GetMainThread(), as there is
no version of that method returning a bare nsIThread* instance.

I didn't introduce one, as we may want to add a lock around mMainThread in the
future, which would require removing nsThreadManager::GetMainThreadWeak. As
this method only returns nsISerialEventTarget, it method could remain
implemented, however, by returning a statically allocated fake event target
which forwards dispatches (and QIs to nsIThread) to the real main thread.
