Support build.sc in Bloop

[lolgab]

After Mill 0.11 mill-contrib-bloop stopped supporting the build module.
Now BloopImpl gets a sequence of Evaluators and gets all modules for all the evaluators in Evaluator.allBootstrapEvaluators, so it supports the build module again.

I'd like to seem some test coverage for a meta-build support.

The newly added test isn't really using a meta-build.

You are right! I was confusing the normal mill build with the meta-build.

Maybe I should change the PR description since what I did is not specific to meta builds.
What do you think?

Yeah, makes sense. If you can move this message into a PR description, we should be good to merge it.

I assume full support for meta-builds should be around the corner, just by the fact that the bootstrap build works. What's needed for confidence is a test case with a meta-build. But this can be another PR.
