Improve method resolution for trait method name bindings

[tritao]

Description

This PR improves method resolution for trait method name bindings, like this following example:

script;

use std::time::Time;

pub fn main() {
    let duration = Time::now().duration_since(Time::from(0)).unwrap();
    let _ = duration + duration;
}

This fix is implemented in Gather trait impls from the argument type module when handling trait operator calls..

A general refactor was also done for associated method resolution functions:

Refactor TypeCheckContext::find_method_for_type.

Refactor resolve_method_name.

Closes #7330.
