Bzlmod support

Adds Bzlmod support to the rules.

Some breaking changes:
* Requires Bazel 7 due to various fixes that are not in 6 that are required for bzlmod to work properly 
* Users will have to regenerate paket2bazel files. If they were using multiple dependency groups they will now be split up into multiple files.
