No signature for resolved procedure groups

[thetarnav]

add_num :: proc (a, b: int) -> int {return a + b}
add_vec :: proc (a, b: [2]f32) -> [2]f32 {return a + b}
add     :: proc {add_num, add_vec}

main :: proc() {
	foo := add(2, 10) // `foo` doesn't show up anything
	bar := add(2, )   // `bar` shows up `int`
}

type of foo is not getting resolved and add has a generic proc signature, instead proc (a, b: int) -> int of the procedure getting resolved.

But when typing the paramenters, the correct signature apprears.

This affects also make, where we don't get to see the inlay hints for default arguments, as we can with new.
