x86/resctrl: Move get_{mon,ctrl}_domain_from_cpu() to live with their callers (2025-03-12 12:24:58 +0100)

----------------------------------------------------------------
- First part of the MPAM work: split the architectural part of resctrl from the
filesystem part so that ARM's MPAM varian of resource control can be added
later while sharing the user interface with x86 (James Morse)
