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: Add CM_ARM_PSD_INFO object2024-01-29T16:47:03+00:00Pierre Gondoispierre.gondois@arm.com2024-01-25T15:18:44+00:00urn:sha1:71ec5d3415c9c012d9dc08a5073c20380eb5d17b
Add an object describing _PSD information, cf. ACPI 6.5,
s8.4.5.5 _PSD (P-State Dependency).
Also add the corresponding CmObjParser.

DynamicTablesPkg: Rename AmlCpcInfo.h to AcpiObjects.h2024-01-29T16:47:03+00:00Pierre Gondoispierre.gondois@arm.com2024-01-25T15:18:43+00:00urn:sha1:e3992e40c7d79f27fa8f923e8a1b0251eb69d7d7
The DynamicTables framework uses the AmlLib to generate some
Aml objects. It is done by using structured known by both
frameworks, e.g. the AML_CPC_INFO/CM_ARM_CPC_INFO structures.
To prepare adding similar structures (e.g. representing _PSD
information), rename AmlCpcInfo.h to AcpiObjects.h. This new
file will contain all the structures used by the AmlLib and
the DynamicTables framework.
