Descrizione

### Which @angular/* package(s) are the source of the bug?

compiler-cli

### Is this a regression?

No

### Description

Any change in main.ts/m1.ts/m2.ts eg changing `console.log(1)` to `console.log(2)` will cause `src/lib/types.ts` to be included in affectedFiles (checked here https://github.com/angular/angular-cli/blob/master/packages/ngtools/webpack/src/ivy/plugin.ts#L569)

Looks like type only file is not included in ignoreForEmit Set nor included in emitted files so IncrementalCompilation can't find it previously emitted files and marks it as affected every time

Inizia con la riproduzione minima sul branch affected-type-repro e analizza packages/ngtools/webpack/src/ivy/plugin.ts intorno alla riga 569, quindi segui come la compilazione incrementale di compiler-cli determina affectedFiles per main.ts, m1.ts, m2.ts e src/lib/types.ts. Il lavoro è completato quando la modifica di console.log(1) in console.log(2) non include più types.ts in affectedFiles.
