Sami Mujawar e3f8605a23 DynamicTablesPkg: Fix issues reported by EDKII CI
The TianoCore EDKII project has introduced a Core CI infrastructure
using TianoCore EDKII Tools PIP modules:
* https://pypi.org/project/edk2-pytool-library/
* https://pypi.org/project/edk2-pytool-extensions/

More information on configuring the environment and running the
builds can be found in edk2\.pytool\Readme.md

This patch fixes the issues reported by the CI system mainly around
fixing typo errors and package dec and dsc files. A subsequent patch
enables the CI builds for the DynamicTablesPkg.

Sami Mujawar dd7523b5b1 DynamicTablesPkg: SRAT: Fix uninitialized memory usage
On enabling the /analyse option the VS2017 compiler
reports: warning C6001: Using uninitialized memory.

This warning is reported for the Status variable in
AddGenericInitiatorAffinity() as it is not initialised
to a default value. This condition is only valid if
GenInitAffCount is equal to 0. Since GenInitAffCount
is already checked in BuildSratTable() this condition
can never happen.

The value of the Status variable is returned in
failure cases from appropriate locations in
AddGenericInitiatorAffinity(). The only case
where Status value is being used un-initialised
is the return statement at the end of
AddGenericInitiatorAffinity().

Therefore, to fix this issue EFI_SUCCESS can be
safely returned instead of returning the Status
variable at the end of the function.

Sami Mujawar 9e7a063b07 DynamicTablesPkg: SRAT: Fix entry points
VS2017 reports 'warning C4028: formal parameter 2 different
from declaration' for the library constructor and destructor
interfaces for the SRAT Generator modules.

Remove the CONST qualifier for the ImageHandle and the
SystemTable pointer in the library constructor and destructor
to make it compatible with the formal declaration.

Sami Mujawar f413d9bee3 DynamicTablesPkg: Arm SRAT Table Generator
The SRAT generator uses the configuration manager protocol
to obtain the affinity information for the GICC, GIC ITS,
Memory, Generic Initiator, etc. and generates the SRAT table.

The table generator supports ACPI 6.3, SRAT table revision 3.

The ACPI and PCI device handles of the Generic Initiator
Affinity structures are represented using tokens. The
generator invokes the configuration manager protocol
interfaces and requests for objects referenced by tokens
to get the device handle information.

The Configuration Manager object definition for the GICC has
been updated to include the Proximity Domain, Clock Domain
and associated flag information. Similarly the Configuration
Manager object for the GIC ITS has been updated to include
the Proximity Domain information. These changes should not
impact any existing implementations as the new fields have
been added towards the end of the Configuration Manager
Objects.
