This represents the different stages that a media data will go through
within the playback journey.

Request Data
RequestData : Record the time where MediaDecoderStateMachine(MDSM) starts
asking for a decoded data to MDSM receives a decoded data.
RequestDemux : Record the time where MediaFormatReader(MFR) starts asking
a demuxed sample to MFR received a demuxed sample. This stage is a sub-
stage of RequestData.
CopyDemuxedData : On some situations, we will need to copy the demuxed
data, which is still not decoded yet so its size is still small. This
records the time which we spend on copying data. This stage could happen
multiple times, either being a sub-stage of RequestDemux (in MSE case),
or being a sub-stage of RequestDecode (when sending data via IPC).
RequestDecode : Record the time where MFR starts asking decoder to return
a decoded data to MFR receives a decoded data. As the decoder might be
remote, this stage might include the time spending on IPC trips. This
stage is a sub-stage of RequestData.
CopyDecodedVideo : If we can't reuse same decoder texture to the
compositor, then we have to copy video data to to another sharable
texture. This records the time which we spend on copying data. This stage
is a sub- stage of RequestDecode.

| TelemetryProbesReporter.h |
This class is used for collecting and reporting telemetry probes for
its owner which should inherit from TelemetryProbesReporterOwner. We use it
for HTMLMediaElement, and each element has one corresponding reporter.
