User Story 37654: Create Extensions base package

- Moved extensions out of MDS solution and directory tree so we can apply different NuGet configs.
- Removed local packages/ from top-level NuGet.config since it is only needed by MDS projects.
- Added a NuGet config for the MDS solution that appends the local packages/ dir as a source.
- Simplified solution and project filenames.
