Fix redundant move animation on Side-FPS indicator

There was a redundant move transition when showing
Side-FPS indicator overlayView on bouncer.
Set PRIVATE_FLAG_NO_MOVE_ANIMATION in Window LayoutParams
when adding overlayView to WindowManager to avoid move
transition.

Test: atest SidefpsControllerTest
Test: manual enable keyguard bouncer and check SFPS indicator
