[PATCH v1 1/1] MdePkg: Add AML FieldList OpCode definitions

["PierreGondois" <pierre.gondois@arm.com>]

From: Pierre Gondois <pierre.gondois@arm.com>

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.
