[no-unused-modules] import type doesn't mark export as used.

[phaux]

Repro:

// Foo.ts
export interface Foo {}

// index.ts
import type { Foo } from "./Foo"

exported declaration 'Foo' not used within other modules

Config:

{
  "extends": [
    "plugin:import/recommended",
    "plugin:import/typescript",
    // and more ...
  ],
  "rules": {
    "import/no-unused-modules": ["error", { "unusedExports": true }],
  },
}

Versions:

@typescript-eslint/parser: 4.8.0
eslint: 7.13.0
eslint-plugin-import: 2.22.1
