UdfpsHelper: Exclude dim layer from screenshots 

The UDFPS dim layer was being captured in screenshots, resulting
in darkened or obscured screenshot content. This occurred because
the dim overlay window was included in the screenshot capture
process.

Use PRIVATE_FLAG_IS_ROUNDED_CORNERS_OVERLAY to exclude the dim
layer from screenshots, screen magnification, and mirroring. This
flag is appropriate for system overlays that should not appear in
captured content, similar to how display cutouts and rounded
corners are handled. It also makes the usage of
PRIVATE_FLAG_EXCLUDE_FROM_SCREEN_MAGNIFICATION redundant.

With this change, screenshots will capture the underlying content
without the UDFPS dimming overlay, providing users with clean
screenshots while maintaining proper UDFPS functionality.
