Set FLAG_DIM_BEHIND for Bidics Prompt window
Biometric prompt used to set a background color
biometric_dialog_dim_color for dim effect, however
the dim background did not cover the statusbar and
navigationbar regions.
Use window manager approach for dim effect:
- Set FLAG_DIM_BEHIND for window layout params
- Set 0.5f dimAmount
- Transit dimAmount when animate away
