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.
