Remove the BufferedInputRouter

Remove the BufferedInputRouter, InputQueue and EventPacket. After further
review and discussion, it's been decided that vsync-aligned input handling would
best be added to the input pipeline via incremental updates, beginning with
event types that currently rely on coaelescing and browser-side buffering.
