MdePkg: Add AML FieldList OpCode definitions
The ACPI specification, version 6.3, January 2019,
defines the Named Objects Encoding for FieldElements
in section '20.2.5.2 Named Objects Encoding'.
FieldElements can be one of the following:
NamedField | ReservedField | AccessField |
ExtendedAccessField | ConnectField
Some of these keywords are starting with an opcode,
allowing to identify their type.
E.g.: ReservedField := 0x00 PkgLength
This patch adds these FieldElement opcodes definitions to
the list of AML Opcode definitions.
