Wire-up window root view surface effects for flexiglass

This will only bring flexiglass implementation to be at parity with pre-25Q3 blur effects.
To match 25Q3 surface effects:
 - Bouncer needs to become transparent, *<->bouncer transitions should be double checked to make sure they emit the correct KTF transition values.
 - Same for glanceable hub as well.
 - Same for shade as well (single shade is opaque now).
 - Shade blur can be noticed for the first few frames while we slow pull down shade, after which it becomes opaque.

Bug: 388068805
Test: verified that windowRootViewBinder is invoked and blur and zoom out effects are applied.
