[PATCH v3 0/4] ArmPkg,ArmVirtPkg: Add support EFI_MP_SERVICES_PROTOCOL on AARCH64

["Rebecca Cran" <rebecca@nuviainc.com>]

Patch 1/4 is the start of addressing the issue that the Aff0 field of
the MPIDR is no longer guaranteed to be the core, and should be referred
to in a more generic way: for example it could be the thread, with Aff1
being the core and Aff2 the cluster. Clearly much more work is needed 
to fully remove that assumption.

Patch 2/4 implements the EFI_MP_SERVICES_PROTOCOL for DXE in Library/MpInitLib.
Patch 4/4 updates CpuDxe to initialize MP support: as a result, it gains
a dependency on MpInitLib.
Patch 3/4 updates ArmVirt.dsc.inc to add the new MpInitLib library.

Cores are powered on and turned off using PSCI.

Note that minimal CPU setup is done: for example the MMU and caches are
left disabled.

--------

Changes from v2:

o Split patches up.
o Wrapped overly long lines.
o Fixed code formatting issues (Uncrustify).
o Fixed other formatting issues (ECC tool).

--------

Testing:

o Ran CI: https://github.com/tianocore/edk2/pull/2312
o Built packages in ArmVirtPkg at each revision for both ARM and AARCH64.
