Apply launch power mode during freezing screen

The most common case of freezing screen is display orientation
change. It usually needs to relaunch activity and redraw windows,
that is similar to the scenario of normal activity launch. So
also apply the "launch" power mode to speed up the procedure.

This can reduce about 10% freezing time for both relaunch and
no-relaunch cases.

Bug: 178472794
Test: Rotate device and check log "Screen frozen for".
