Reduce `clarity-repl` scope and coupling

[hugo-stacks]

clarity-repl is the biggest component of Clarinet (~15k LoC, 28% of the project).

As a result it can be long to build.
Additionally, many other components depend on it.

• Set some default constant in their own component chore: new clarinet-defaults #2217
• Directly import clarity from clarity instead of clarity-repl::clarity refactor: don't expose clarity crate from clarity-repl #2260
• Move ast_visitor (or the all ::analysis eventually) in its own components since it's isolated code and many other components depend on it
• Move dependency_detector in it's component since it's isolated code

Eventually, the goal is have smaller, more focused components, and reduce coupling between each.

This has two goals:

• make the code base easier to navigate
• speed up the feedback loop by reducing compile time

Running

$ touch components/clarity-repl/src/repl/mod.rs && cargo build --timings
$ open target/cargo-timings/cargo-timing.html 

touch a clarinet-repl file to force the rebuild.
Result obviously depends on the machine used itself
