Missing JSC_MISSING_REQUIRE when importing `@interface` type via `goog.requireType` in a `goog.module`

The following code, [when compiled with `CHECK_REQUIRES`, produces a `JSC_MISSING_REQUIRE_IN_PROVIDES_FILE` warning](https://closure-compiler-debugger.appspot.com/#input0%3Dgoog.provide('Interface')%253B%250A%250A%252F**%2520%2540interface%2520*%252F%250AInterface%2520%253D%2520function()%2520%257B%257D%253B%250A%26input1%3Dgoog.requireType('Interface')%253B%250A%250A%252F**%2520%2540constructor%2520%2540implements%2520%257BInterface%257D%2520*%252F%250Afunction%2520Implementation()%2520%257B%257D%250A%26conformanceConfig%26externs%26refasterjs-template%26CHECK_TYPES%3Dtrue%26REWRITE_MODULES_BEFORE_TYPECHECKING%3Dtrue%26CHECK_REQUIRES%3Dtrue%26CLOSURE_PASS%3Dtrue%26PRESERVE_TYPE_ANNOTATIONS%3Dtrue%26PRETTY_PRINT%3Dtrue):

```JS

Interface = function() {};
```

Child:
```
goog.requireType('Interface');

/** @constructor @implements {Interface} */

```

Warnings:
```

~~I believe this warning is spurious, because [it does not occur if you use `goog.require` instead of `goog.requireType`](https://closure-compiler-debugger.appspot.com/#input0%3Dgoog.provide('Interface')%253B%250A%250A%252F**%2520%2540interface%2520*%252F%250AInterface%2520%253D%2520function()%2520%257B%257D%253B%26input1%3Dgoog.require('Interface')%253B%250A%250A%252F**%2520%2540constructor%2520%2540implements%2520%257BInterface%257D%2520*%252F%250Afunction%2520Implementation()%2520%257B%257D%250A%26conformanceConfig%26externs%26refasterjs-template%26CHECK_TYPES%3Dtrue%26REWRITE_MODULES_BEFORE_TYPECHECKING%3Dtrue%26CHECK_REQUIRES%3Dtrue%26CLOSURE_PASS%3Dtrue%26PRESERVE_TYPE_ANNOTATIONS%3Dtrue%26PRETTY_PRINT%3Dtrue), even though the import is used only for type annotation, and [it does not occur if you use `goog.module` instead of `goog.provide`](https://closure-compiler-debugger.appspot.com/#input0%3Dgoog.module('Interface')%253B%250A%250A%252F**%2520%2540interface%2520*%252F%250Aconst%2520Interface%2520%253D%2520function()%2520%257B%257D%253B%250Aexports%2520%253D%2520Interface%253B%250A%26input1%3Dgoog.module('main')%253B%250Aconst%2520Interface%2520%253D%2520goog.requireType('Interface')%253B%250A%250A%252F**%2520%2540constructor%2520%2540implements%2520%257BInterface%257D%2520*%252F%250Afunction%2520Implementation()%2520%257B%257D%253B%250A%26conformanceConfig%26externs%26refasterjs-template%26CHECK_TYPES%3Dtrue%26REWRITE_MODULES_BEFORE_TYPECHECKING%3Dtrue%26CHECK_REQUIRES%3Dtrue%26CLOSURE_PASS%3Dtrue%26PRESERVE_TYPE_ANNOTATIONS%3Dtrue%26PRETTY_PRINT%3Dtrue).~~
