window: move size reporting to animation begin callback (#9298)

* window: fix resizes with an update callback

* window: fixup sendWindowSize

Remove the size argument from sendWindowSize, since it is now a member of the Window class
and we don't want any mismatches between m_vRealSize and what we report.

Remove sendWindowSize from mapWindow, since we shouldn't need it.

* window: sendWindowSize on animation begin

* window: move most calls to sendWindowSize to the animation begin
callback

* window: remove sendWindowSize in unmanaged if not fullscreen
