docs: fix mailing lists URLs

With the transition to mailman3, the URLs of TF-A and TF-A Tests
mailing lists have changed. However, we still refer to the old
location, which are now dead links.

Update all relevant links throughout the documentation.

There is one link referring to a specific thread on the TF-A mailing
list in the SPM documentation, for which I had to make a guess as to
what's the equivalent mailman3 URL. The old URL scheme indicates that
the thread dates from February 2020 but beyond that, I could not make
sense of the thread id within the old URL so I picked the most likely
match amongst the 3 emails posted on the subject in this time period.

Extract the UUID from the SP layout JSON file if the optional 'uuid'
field exists otherwise fall back to the current method for extracting
the SP UUID from the partition manifest file.

This change gives a way to decouple TF-A's dependency on the SP
manifest file's format which is tied to the SPMC.

refactor(spmd): boot interface and pass core id

This change refactors the SPMD to setup SPMC CPU contexts once and early
from spmd_spmc_init (single call to cm_setup_context rather than on each
and every warm boot).
Pass the core linear ID through a GP register as an implementation
defined behavior helping FF-A adoption to legacy TOSes (essentially
when secure virtualization is not used).

A first version of this change was originally submitted by Lukas [1].
Pasting below the original justification:

Our TEE, Kinibi, is used to receive the core linear ID in the x3
register of booting secondary cores.
This patch is necessary to bring up secondary cores with Kinibi as an
SPMC in SEL1.

In Kinibi, the TEE is mostly platform-independent and all platform-
specifics like topology is concentrated in TF-A of our customers.
That is why we don't have the MPIDR - linear ID mapping in Kinibi.
We need the correct linear ID to program the GICv2 target register,
for example in power management case.
It is not needed on GICv3/v4, because of using a fixed mapping from
MPIDR to ICDIPTR/GICD_ITARGETSRn register.

For debug and power management purpose, we also want a unified view to
linear id between Linux and the TEE.
E.g. to disable a core, to see what cores are printing a trace /
an event.

In the past, Kinibi had several other designs, but the complexity was
getting out of control:
* Platform-specific assembler macros in the kernel.
* A per-core SMC from Linux to tell the linear ID after the boot.
* With DynamiQ, it seems SIPs were playing with MPIDR register values,
reusing them between cores and changing them during boot.
