Prevents the binder call fail from freeze when send app visibility. 

The client visibility state could remains GONE if the binder call
IWindow#dispatchAppVisibility fail. A possible reason is the binder is
still freeze and the buffer is fulled.
Try to unfreeze the process binder call before set visibility change,
so and top resumed.

Bug: 225530340
Test: verifyapps to dispatch app visibility happen after unfreeze.
