feat: module recipe dependency support

[corvusrabus]

Support for recipe dependencies in a submodule

mod foo

baz: foo::bar

Contributes to #2252

Still needs a bit of work.

Sorry. Took me a while to come back to this. I think it's ready for review now @casey

Hey @casey. Any chance you have time to have a look :) ?

Nice work! I refactored resolve_recipe to delegate to another function resolve_dependency which makes it a little cleaner and gets rid of some nesting, but otherwise looks great!
