docs(context-mgmt): add documentation for context management library

This patch adds some documentation for the context management library.
It mainly covers the design at a higher level, with more focus on
the cold boot and warm boot entries as well as the operations
involved during context switch. Further it also includes a section
on feature enablement for individual world contexts.

refactor(smccc): move debugfs to vendor el3 calls

Move debugfs to Vendor-Specific EL3 Monitor Service Calls.
Function Identifier for Vendor-Specific EL3 Monitor Service is '7' and
allocated subranges of Function identifiers to different services are:

0x87000000-0x8700FFFF-SMC32: Vendor-Specific EL3 Monitor Service Calls
0xC7000000-0xC700FFFF-SMC64: Vendor-Specific EL3 Monitor Service Calls

Amend Debugfs FID's to use this range and id.

Add a deprecation notice to inform debugfs moved from arm-sip range to
Vendor-Specific EL3 range. Debugfs support from arm-sip range will be
removed and will not be available after TF-A 2.12 release.

feat(mpmm): add support for MPMM

MPMM - the Maximum Power Mitigation Mechanism - is an optional
microarchitectural feature present on some Armv9-A cores, introduced
with the Cortex-X2, Cortex-A710 and Cortex-A510 cores.

MPMM allows the SoC firmware to detect and limit high activity events
to assist in SoC processor power domain dynamic power budgeting and
limit the triggering of whole-rail (i.e. clock chopping) responses to
overcurrent conditions.

This feature is enabled via the `ENABLE_MPMM` build option.
Configuration can be done via FCONF by enabling `ENABLE_MPMM_FCONF`, or
by via the plaform-implemented `plat_mpmm_topology` function.
