Config handling updated to using repository for hydration (#12714)

* Modification to allow src/config to be a repo within a repo.

* Moving config files to own repository, and including using make.

* Removing all old config files.

* Correct CI errors.

* Playing with pulling the configuration files from the API

* Attempt to get past github actions issue

* Adding additional assistance when configs not hydrated

* Move the workflow to support hydration before outputing target list.

* Correction for revision targets

* Requires additional config hydration

* Better messaging on what to do:

- when you have a local config.h for a new target, ignore hydration of target list if you are building the target config in question.
- when you are doing any activity that does not require hydration, e.g. printing out help or installing arm_sdk etc.

* Anything suffixed with clean should be allowed through

* Adjusting to simply use a copy of the repository. Noting we will need to decide whether or not to include MFTR name in the config directory or not.
