Add argument typechecking for all predefined ACPI names.

Fully implements typechecking on all incoming arguments for all
predefined names. This ensures that ACPI-related drivers are
passing the correct number of arguments, each of the correct
object type.

Argument counts are checked for the incoming arguments as well
as for the actual ASL definition of the ACPI name itself
(it must match the ACPI specification).
