DynamicTablesPkg/AmlLib: Implement C-State and P-State ACPI object
This commit introduces a set of functions designed to facilitate the creation
and management of C-State (_CST, _CSD) and P-State (_PCT, _PSS) ACPI objects.
Detailed Summary:
1) AmlCreateCstNode(): This function is responsible for creating a _CST
(C-State) node, which is essential for defining processor idle states.
2) AmlAddCstState(): This function adds a C-State package to an existing
CST node, allowing for the specification of individual C-State entries.
3) AmlCreateCsdNode(): This function creates a _CSD (C-State Dependency) node,
which is used to describe dependencies between different C-States.
4) AmlCreatePctNode(): This function generates a _PCT (Performance Control)
node,
complete with PCT packages, to manage performance state transitions.
5) AmlCreatePssNode(): This function creates a _PSS (Performance Supported
States) node,
which lists the supported performance states for a processor.

DynamicTablesPkg: Adds C-state and P-state namespace objects
This update adds new configuration manager objects for C-State and P-State.
The C-State objects manage processor idle states,
while the P-State objects handle processor performance states.
This enhancement improves power management and performance
tuning within the DynamicTablesPkg.
Changes include:
- Added C-State and P-State namespace objects in ArchCommonNameSpaceObjects.h.
- Updated ConfigurationManagerObjectParser.c to support the new objects.
- Revised Readme.md to document these changes.

Log Message:
-----------
DynamicTablesPkg: Add _CST, _CSD, _PCT, and _PSS objects
This patch adds several ACPI objects to the X64 CPU SSDT table
to enhance power and performance management.
The new objects include:
- _CST: Defines CPU idle states for power saving.
- _CSD: Specifies dependencies between CPU idle states.
- _PCT: Provides an interface for controlling CPU performance states.
- _PSS: Lists supported CPU performance states.
- _PPC: Indicates current CPU performance capabilities.
These additions help improve power efficiency and thermal management in X64
systems.
