Log Message:
-----------
DynamicTablesPkg/AmlLib: Add AmlMethodParamTypeBuffer support
Extend AML_METHOD_PARAM_TYPE enum with AmlMethodParamTypeBuffer (= 4)
to allow callers to pass a raw byte Buffer as an AML method argument.
Add a Buffer case to the switch in AmlCodeGenInvokeMethod() that
delegates to the existing AmlCodeGenBuffer() helper, with NULL-pointer
and zero-length guards matching the pattern of the other cases.
AmlCodeGenReturnInvokeMethod() already delegates to AmlCodeGenInvokeMethod()
so it picks up the new case automatically.
Update AML_METHOD_PARAM documentation: clarify that DataSize carries the
byte count when Type is AmlMethodParamTypeBuffer, and update the
union/struct field comments accordingly.
