Change the AML_DEBUG_STR() macro to AML_OPCODE_DEF() that takes a string
and the AML OpCode as input so that the text description and the AML
OpCode are grouped. The AML_OPCODE_DEF() macro also strips the string
description for release builds.

ASL is a source language for defining ACPI objects including
writing ACPI control methods. An ASL file is compiled using
an ASL compiler tool to generate ACPI Machine Language (AML).
This AML bytecode is processed by the ACPI AML interpreter
that runs as part of an Operating System (OS).
Both ASL and AML are declarative languages. Although they
are closely related they are different languages.
ASL statements declare objects. Each object has three parts,
two of which can be NULL:
Object := ObjectType FixedList VariableList
The AML grammar defines corresponding encodings that makes
up the AML byte stream.
This patch introduces the AML grammar definitions used by
AmlLib for encoding/decoding AML byte streams.
