Function def_path_res_with_base

pub fn def_path_res_with_base(
    tcx: TyCtxt<'_>,
    base: Vec<Res>,
    path: &[&str],
) -> Vec<Res>

Resolves a def path like vec::Vec with the base std.

This is lighter than def_path_res, and should be called with find_crates looking up items from the same crate repeatedly, although should still be used sparingly.
