DynamicTablesPkg: AmlEncoding change debug macro
    
    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.
