Elias Naur 5f6fa25209 app/internal/window: [wasm] have at most one animation callback in flight
Track whether requestAnimationCallback has been called when SetAnimating
changes the animated state of the window. Multiple callbacks result in wasteful
redraws.

Without this change, my browser becomes unresponsive when Window.Invalidate
is called every frame. Calling Invalidate every frame is a misuse (InvalidateOp
should be used for animation), but it's nice to have reasonable behaviour.

This change might also fix the issues described in
https://github.com/gioui/gio/pull/7.
