Allow users to customize coursier ResolutionParams

[alexarchambault]

This adds a JavaModule#resolutionParams task, allowing users to customize coursier's ResolutionParams. These allow to customize some aspects of dependency resolution.

In particular, ResolutionParams#enableDependencyOverrides, when set to Some(false), disables the recent BOM changes added (and enabled by default) in coursier 2.1.17. This might be useful, if ever users aren't happy with the versions it selects, or want to wait a bit before enabling that, or if they find out performance suffers because of it for them.

The new task is anonymous (it's not a target, it's not serialized on disk), as ResolutionParams has a field that doesn't easily lend itself to serialization (rules, because of the Rule type, which is an open abstract class).

I think you should move the resolutionParams task into CoursierModule, since that the place where it should be used. This would also avoid the introduction of new resolutionParams parameter which the default parameter in various places.

The new task should definitely come with some documentation, since some other customizations seem to affect the final ResolutionParams as well. What overrides what?
