Make wallpaper default frame rate configurable

This change introduces a configuration option to adjust the frame rate
compatibility value for Wallpaper BBQ wrapper.
The frame rate value can be adjusted via RRO, providing more flexibility
in managing wallpaper performance across different device configurations.
The default value is FRAME_RATE_COMPATIBILITY_MIN (102) for lower power
consumption.

Bug: 326279062
Test: manual (check fps on live wallpapers)
Flag: NA (AOSP contribution from Sony)
