Make a copy for draw transaction of local window

Because local window means that ViewRootImpl lives in the same
process. The transaction sent from ViewRootImpl#reportDrawFinished
is the same instance as WindowState#finishDrawing receives.

Then if the transaction is cleared before applying, the blast sync
will be broken and block render thread.

Bug: 234585256
Test: adb shell setprop persist.wm.debug.shell_transit 1; reboot
      Enable "Pointer location" in developer options.
      Rotate display many times and no any timeout.
