sort completions based on the result location type at the current cursor position

[Techatrix]

In the following code snippet, in which order should the completions be ordered?

const large_number: u64 = 0;
const small_number: u32 = 0;
const byte: u8 = 0;
const string: []const u8 = "";
fn foo(_: u32) u32 {}
test {
    foo(<cursor>);
}

byte, small_number and foo() should come first because only they can coerce to the result location type u32.

const some_variable: u32 = 5;
const some_type: type = u32;
const T: <cursor> = undefined;

some_type should come first because it can coerce to the result location type type.

I can imagine many possible sorting rules on how to use RLS to improve completion and this example is just one of many.
