list frozen modules in the support matrix

- fix the list of frozen modules in the board info, separate it from the builtin modules
- frozen modules are listed along with the link to their repository
- get the repository by running the git command in the frozen directory
- frozen modules are listed at the end
- they copy the style of the other modules
- frozen modules in build_board_info don't need the URLs, they are filtered out
