feat(spm): separate StMM SP specifics to add support for a S-EL0 SP
This patch separates the code from SPM_MM to get xlat table context and
move it to a common location. In addition, only APIs required from both
SPM_MM and FF-A EL3 SPMC are moved to the common location.
This allows understanding better what is required to support a S-EL0 SP
instead of trying to retrofit what already exists.
