Implement should_continue in chalk-recursive

[detrumi]

This just returns NoSolution if it shouldn't continue, but that should already be useful to rust-analyzer.

Note: Cloning of should_continue is a workaround to a rustc bug (#95734)

[detrumi]

Build failed because of #775

Alright, changed it to Ok(Ambig). As for refactoring, would it be useful to add Solution::QuantumExceeded, like AnswerResult::QuantumExceeded in chalk-engine?
