refactor(pkg_aliases): create a macro for creating whl aliases (#2391)
This just cleans up the code and moves more logic from the repository_rule (i.e. generation of `BUILD.bazel` files) to loading time (macro evaluation). This makes the unit testing easier and I plan to also move the code that is generating config setting names from filenames to this new macro, but wanted to submit this PR to reduce the review chunks. Summary: - Add a new `pkg_aliases` macro. - Move logic and tests for creating WORKSPACE aliases. - Move logic and tests bzlmod aliases. - Move logic and tests bzlmod aliases with groups. - Add a test for extra alias creation. - Use `whl_alias` in `pypi` extension integration tests. - Improve the serialization of `whl_alias` for passing to the pypi hub repo. Related to #260, #2386, #2337, #2319 - hopefully cleaning the code up will make it easier to address those feature requests later. --------- Co-authored-by: Richard Levasseur <[email protected]>
