OvmfPkg/ResetSystemLib: rename to BaseResetSystemLib

In preparation for introducing DxeResetSystemLib, rename the current
(only) ResetSystemLib instance to BaseResetSystemLib.

In the DSC files, keep the ResetSystemLib resolution in the same
[LibraryClasses] section, but move it near the TimerLib resolution, as the
differences between the ResetSystemLib instances will mostly follow those
seen under OvmfPkg/Library/AcpiTimerLib.

(While OvmfXen does not use "OvmfPkg/Library/AcpiTimerLib", perform the
same movement there too, for keeping future DSC diffing simple.)
