Remove DFCI Python Scripts (#397)

## Description

The SettingSupport directory in SetupDataPkg was brought over from
mu_feature_dfci to allow reusing the UEFI variable support access from
Python. However, this was moved into edk2-pytool-library and none of the
other scripts are needed here. Any users of them should use the updated
scripts in mu_feature_dfci.

- [ ] Impacts functionality?
- [ ] Impacts security?
- [x] Breaking change?
- [ ] Includes tests?
- [ ] Includes documentation?

## How This Was Tested

N/A.

## Integration Instructions

Any users of the SettingSupport scripts should consume them from
mu_feature_dfci.
