[PATCH v1 03/11] MdePkg/Acpi64: Add _PSD/_CPC/State Coordination Types macros

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

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

Add macros for:
- _PSD version
- _CPC version
- C-state/T-state/P-state Coordination Types

These objects were present in previous ACPI specification version,
but are only added to the latest availbable version (6.4).
