spm: Remove SPM Alpha 1 prototype and support files

The Secure Partition Manager (SPM) prototype implementation is
being removed. This is preparatory work for putting in place a
dispatcher component that, in turn, enables partition managers
at S-EL2 / S-EL1.

This patch removes:

- The core service files (std_svc/spm)
- The Resource Descriptor headers (include/services)
- SPRT protocol support and service definitions
- SPCI protocol support and service definitions

Remove dependency between SPM_MM and ENABLE_SPM build flags

There are two different implementations of Secure Partition
management in TF-A. One is based on the "Management Mode" (MM)
design, the other is based on the Secure Partition Client Interface
(SPCI) specification. Currently there is a dependency between their
build flags that shouldn't exist, making further development
harder than it should be. This patch removes that
dependency, making the two flags function independently.

Before: ENABLE_SPM=1 is required for using either implementation.
By default, the SPCI-based implementation is enabled and
this is overridden if SPM_MM=1.

After: ENABLE_SPM=1 enables the SPCI-based implementation.
SPM_MM=1 enables the MM-based implementation.
The two build flags are mutually exclusive.

Note that the name of the ENABLE_SPM flag remains a bit
ambiguous - this will be improved in a subsequent patch. For this
patch the intention was to leave the name as-is so that it is
easier to track the changes that were made.
