MCAsmParser: support required parameters
This enhances the macro parser to parse and handle parameter qualifications,
which is needed to support required formal parameters in macro definitions. A
required parameter may not be defaulted (though providing a default value is
accepted with a warning). This improves GAS compatibility.
Partially addresses PR9248.
