ArmPkg/Library: optimise StandaloneMmMmuLib with FF-A v1.3
commit 4ca452c ("ArmPkg/Library: Update StandaloneMmuLib with
FF-A v1.2 with page granularity") introduced page-granular memory
permission updates to fix the StandaloneMm load failure.
However, this approach results in issuing an SMC call
per page when updating permissions over a region.
Since FF-A Memory Management Protocol v1.3 [0],
FFA_MEM_PERM_GET has been updated to return the number of contiguous
pages that share the same memory permission starting from a base address.
With this change, update memory permissions in bulk
(per contiguous page range) to reduce the number of SMC calls,
leveraging FF-A Memory Management Protocol v1.3 [0].

ArmPkg,MdePkg,MdeModulePkg: change ArmFfaLibGetVersion() with whole version
Current ArmFfaLibGetVersion()'s arguments receive two arguments
-- major version and minor version.
However, This gives some impression treating major and minor version
of the ABI as two unrelated 16-bit variables as opposed to
the upper and lower 16-bits of a 32-bit version variable.
Therefore, change the arguments with whole version and
let user to get major/minor version via ARM_FFA_MAJOR/MINOR_VERSION_GET
macros.
Also, add some useful helper to check version compatibility and
mimimum require ABI version.
