ACPICA: Predefine names: Add allowed argument types to master info table

This change adds the infrastructure to enable typechecking
on incoming arguments for the predefined methods/objects. It
does not actually contain the code that will fully utilize this
information. Also condenses some duplicate code for the predefined
names into a new module, utilities/utpredef.c
