bug(semantic): `typeof` operator on type imports not counted as a reference

[DonIsaac]

Part of #4445. Found by @camc314.

import type { mySchema } from './my-schema';
function test(arg: ReturnType<typeof mySchema>) {
  //                          ^^^^^^^^^^^^^^^ should be a `Type` reference
    arg;
}
test('');

Note that non-type imports work as expected:

import { mySchema } from './my-schema';
function test(arg: ReturnType<typeof mySchema>) {
    arg;
}
test('');

This usage looks weird, but typescript supports it, and so must we.
