ArmPkg: split off ArmGicArchLib from ArmGicLib
The current implementation of ArmGicGetSupportedArchRevision () that is used by all ARM platforms is entirely stateless (in order to support being executed from flash) so it needs to interrogate the hardware for the supported GIC revision upon each invocation. However, this statelessness is only needed for SEC type modules; in all other cases, we could easily determine the GIC revision once, and store the result in a global variable. In preparation of having separate early and normal versions, this patch introduces the ArmGicArchLib library class and default implementation, and moves the existing ArmGicGetSupportedArchRevision () into it.
