OvmfPkg: AcpiTimerLib: Use global variable during PEI_CORE and PEIM
Since in OVMF both PEI_CORE and PEIM run from RAM, and thus may
utilize global variables, use the "Base" AcpiTimerLib instance
(instead of BaseRom) to take advantage of the improved efficiency
of storing the timer register IO address in a global variable.
This leaves only SEC using the BaseRomAcpiTimerLib instance.
