feat(lfa): add initial implementation for LFA_PRIME

This patch introduces the overall handling of the LFA_PRIME call,
including input validation and invocation flow.
While this covers the core implementation, per-component-specific
handling will be developed in a separate patch. The respective
component callbacks are invoked as part of this logic.

feat(lfa): implement LFA_GET_INVENTORY SMC

This implementation primarily retrieves activation-related flags for
a given fw_seq_id, including whether the firmware is activation
capable, whether an update is pending activation, whether it resets
the CPU during activation, whether CPU rendezvous is required, and the
firmware's UUID.
To support this, a platform API is called to determine whether an
update is available for the specified fw_seq_id, indicating its
pending activation status.

feat(fvp): initialize LFA component activators in platform layer

Update the FVP platform's LFA component table to populate the
'activator' and 'activation_pending' by introducing fields
in plat_lfa_component_info_t.
- 'activator': function pointers for component-specific
activation logic
- 'activation_pending': tracks whether the component's activation
is pending

Set the activator function pointers for supported components:
- BL31 via get_bl31_activator()
- RMM (if RME is enabled) via get_rmm_activator()

This allows the LFA service to invoke component-specific prime
and activate callbacks through platform-registered hooks.

activation by passing lfa_component_status details.

perf(bl31): convert cpu_data fetching to C

The assembly routines are opaque to the compiler and it can't inline
them. There is also no requirement for them to be called without a
stack - each of their calls has a stack available. So convert them to C
so that the compiler can do its inlining magic.

On AArch32 we need to be able to call _cpu_data from the entrypoint so
it has to stay as a slight exception.

We can also straighten out the type of the cpu_ops_ptr member so we
don't have to cast it everywhere.

The pwrdwn_req_received variable is used across multiple platforms

API to access this variable across the platforms, and restrict the
scope of variable to the particular file by defining it as static
variable. This prevents unintended access of variable from other
files and increase safety.
