[StableMIR] API to retrieve definitions from crates

Add functions to retrieve function definitions and static items from all crates (local and external).

For external crates, we're still missing items from trait implementation and primitives.

r? ````@compiler-errors:```` Do you know what is the best way to retrieve the associated items for primitives and trait implementations for external crates? Thanks!
