Provide a quick fix for 'module does not refer to a type'

[DanielRosenwasser]

// ./foo.ts

export async function bar() {
    let foo: import("./foo") = await import("./foo");
//           ^^^^^^^^^^^^^^^
// Module './foo' does not refer to a type, but is used as a type here.
}

We should give a quick fix in this scenario.

change it to typeof import("./foo") if applicable.
