Pierre Gondois 740e3bb634 DynamicTablesPkg: DynamicPlatRepo: Add TokenFixer
The DynamicPlatRepo library allows to handle dynamically created
CmObj. The dynamic platform repository can be in the following states:
1 - Non-initialised
2 - Transient:
    Possibility to add CmObj to the platform, but not to query them.
3 - Finalised:
    Possibility to query CmObj, but not to add new.

A token is allocated to each CmObj added to the dynamic platform
repository (except for reference tokens CmObj). This allows to retrieve
dynamic CmObjs among all CmObj (static CmObj for instance).

This patch add the TokenFixer files, allowing to update the
self-token some CmObj have.
