Add support for global excluding of transitive dependencies

[Gedochao]

Is your feature request related to a problem? Please describe.
We'd like a way to globally exclude transitive dependencies, rather than doing it via individual dep param (exclude=*, as described in https://scala-cli.virtuslab.org/docs/guides/introduction/dependencies/#excluding-transitive-dependencies).

Describe the solution you'd like

• using directive: //> using dep.exclude org.scala-lang.modules::scala-collection-compat:2.12.0
• command line option: --dependency-exclude org.scala-lang.modules::scala-collection-compat:2.12.0
• passing the dependency without an explicit version should exclude it independent of the transitive version, i.e.: //> using dep.exclude org.scala-lang.modules::scala-collection-compat would get rid of all transitive scala-collection-compat

Describe alternatives you've considered
Keep excluding per dependency, when necessary.

Additional context
Initially suggested by @prolativ.

Not sure if we have actual way to exclude a specific version, does coursier have an API for that?

[prolativ]

This should also work with other variants of dep, e.g. compileOnly.dep.exclude or test.dep.exclude

[prolativ]

Shouldn't the command line option be named --dep-exclude? Or maybe we should at least have such an alias?
In order to keep symmetry with --compile-dep, while --compile-dependency is missing

yeah, we should have an alias in compliance with --dep/--dependency.
I suppose --compile-dependency is a missing alias, here.
