feat(rme): add ENABLE_RME build option and support for RMM image
The changes include:
- A new build option (ENABLE_RME) to enable FEAT_RME
- New image called RMM. RMM is R-EL2 firmware that manages Realms.
When building TF-A, a path to RMM image can be specified using
the "RMM" build flag. If RMM image is not provided, TRP is built
by default and used as RMM image.
- Support for RMM image in fiptool
