Refactor: Move CPack internal files to `Internal/CPack/` directory

Some commits ago all CPack internal `*.cmake` files have been moved
to `Internal/CPack/`. This commit also move some templates
internally used by generators to the same location to make
`Modules/` directory less noisy w/ files the end users don't
need to use/see.
