[perf] Add a SceneDisplayLag event when we miss vsyncs (#17575)
This event goes from now -> current vsync target time
to avoid the limitations as seen in https://github.com/flutter/flutter/issues/54095#issuecomment-610636237

This event also tags additional metadata to capture
`vsync_transitions_missed` considering the refresh rate of the display.
