ArmPkg: MmCommunicationDxe: Fix Comm Buffer Init
Currently, MmCommunicationDxe expects the MM comm buffer
to either be not added by the platform or added and allocated
by the platform. However, not all platforms follow this pattern.
This commit makes the handling more generic by checking to see
if a GCD descriptor exists that covers this range. If it does,
the capabilities are updated as needed. If only a partial desc
exists for this range, the driver will fail as that is a platform
misconfiguration.
If the descriptor does not exist, the driver will add the buffer.
Then, for all successful cases, the attributes are updated on the
buffer to what the driver expects them to be.
