feat(lfa): add LFA holding pen logic

Add LFA holding logic to be used by the LFA activate SMC call to manage
CPU rendezvous. All CPUs are expected to invoke the LFA activate call
for the rendezvous, until then, they will remain on a holding lock.
When the final CPU calls LFA activate, it will release the holding
lock after completing the activation process on that CPU, allowing
the activation process on secondary CPUs to proceed.

feat(lfa): implement LFA_GET_INFO SMC and integrate LFA build

Implement the LFA_GET_INFO SMC handler, which retrieves the
number of supported firmware components and performs initial
setup via the platform APIs. This forms the entry point for
LFA usage and makes component metadata available for later use.

Update the build system to include LFA sources.

feat(lfa): create LFA SMC handler template

As per the specification v1.0[1], added all Live Firmware Activation
(LFA) SMCs, including their Function IDs (FIDs) and associated error
codes.
A dummy handler function has been created as a template. Subsequent
patches will implement the handling of these SMCs.
