Use update PlatformBuild/CIsettings to limit recursive downloading

[apop5]

Description

Use updated stuart tools to limit recursive downloading from mu repositories.

When a platform identifies submodules through GetRequiredSubmodules()
it previously only contained True/False for specifying the need for
submodules. If True, it would recursively clone all submodules.

This modification allows specifying a CiSettings file containing a
CiSetupSettingsManager instance, and will attempt to only download
the submodules specified in the GetRequiredSubmodules section.

GetDependencies() does not have configuration for this type of scenario.
A Dependency from GetDependencies will always attempt to resolve ALL submodules that are contained in the repo.

This presents a problem when a submodule contains their own dependency as well. The example run into is:

SecurityPkg => libspdm
libspdm => openssl
openssl => gost-engine
gost-engine => libprov
