Emircan Uysaler 929a86d3fc [fuchsia] Restructure Flatland vsync loop (flutter/engine#45531) ...

This CL restructures Flatland vsync loop to fire for each vsync instead
of each OnNextFrameBegin. As shown in the traces attached to the bug,
the current implementation of firing callbacks on each OnNextFrameBegin
causes skips when Flutter has longer draw calls. By scheduling frames in
between, we are increasing the chance of sending one before the latch
point. OnNextFrameBegin is now used to keep track of present credits and
future presentation times as well as when to start frame, replacing the
need for max_frames_in_flight and vsync_offset fields.
