FrameStatisticsData can now store inter-keyframe information, which is
provided by the MediaFormatReader (based on live decoding).

Decoders now use FrameStatisticsData to gather data for their frame-related
notifications. This will ease introducing new members later on.

Decoders uses 64-bit values to count frames, so we should use the same type
in FrameStatistics.
Because VideoPlaybackQuality can only use 32 bits (as defined in W3C specs),
we need to ensure that imported FrameStatistics numbers can fit in 32 bits,
while keeping their ratios the same.

Move FrameStatistics' data into separate struct, so that it can more easily be
changed and passed around, outside of the lock-controlled FrameStatistics
object.
