importsNotUsedAsValues = error should apply to export statements

TypeScript Version: 3.9.2

Search Terms: importsNotUsedAsValues, error, export

Code

import { Interface } from "./module";
export { Interface } from "./module";

With a "importsNotUsedAsValues" set to "error".

Expected behavior:

tsc would error on the export statement.

Actual behavior:

tsc does not error on the export statement, it only errors on the import statement. TypeScript, by default, would elide both statements in the compile and should error in the same way.

Playground Link: N/A

Start by reproducing the supplied two-statement example with TypeScript 3.9.2 and the importsNotUsedAsValues setting. Trace the compiler path that reports the option for the import and compare it with the export statement, then locate the relevant compiler tests. Done means the export statement reports the same error under the setting without regressing existing behavior.
