Uses Android.bp vintf_compatibility_matrix for redfin product FCM.

This change also includes the following FCM cleanups:
- Adds level="6", specifying that this product FCM is compatible with an
  S vendor image. This is similar to the framework FCM.
- Marks the HAL as required. This is possible now that the redfin_vf
  target includes an additional product FCM specific to level="5" (R).

Bug: 183507590
Test: m redfin
Test: m redfin_vf, merge with R vendor half
