minui: Use runtime properties instead of build time vars.

This CL removes the use of the following build time macros, and uses the
runtime property values instead.
- TARGET_RECOVERY_PIXEL_FORMAT
- TARGET_RECOVERY_OVERSCAN_PERCENT
- TARGET_RECOVERY_DEFAULT_ROTATION

Bug: 110380063
Test: Set up taimen with `TARGET_RECOVERY_DEFAULT_ROTATION := ROTATION_LEFT`.
      Build and check recovery UI.
Test: Set up taimen with `TARGET_RECOVERY_PIXEL_FORMAT := ABGR_8888`.
      Build and check recovery UI.
