perf/x86/intel: Use the common uarch name for the shared functions

>From PMU's perspective, the SPR/GNR server has a similar uarch to the
ADL/MTL client p-core. Many functions are shared. However, the shared
function name uses the abbreviation of the server product code name,
rather than the common uarch code name.

Rename these internal shared functions by the common uarch name.
