SF: Skip modesetting during boot animation

`bootanimation` does not support resizing itself on resolution switch,
so defer initiating DM's request for max resolution until the animation
has finished.

Fixes: 421256337
Flag: com.android.graphics.surfaceflinger.flags.synced_resolution_switch
Test: Select "Max resolution" in Settings and reboot
