do not resolve aliases when renaming symbol

[Techatrix]

closes #3184

Example:

const S = struct {
    fn foo() void {}
};
comptime {
    const foo = S.foo;
    foo();
}

• Renaming foo() will only rename foo() and const foo
• Renaming fn foo is unchanged and will rename all four locations
• References is also unchanged and will provide all four locations no matter where it has been requested.
