AngularCompiler marks not related files as affected in incremental build

### 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

### Anything else?

This is followup to this issue https://github.com/angular/angular/issues/42543 which was partially resolved by JoostK PR https://github.com/angular/angular/pull/42759

先在 affected-type-repro 分支上從最小重現開始，並檢查 packages/ngtools/webpack/src/ivy/plugin.ts 第 569 行附近的程式碼，接著追蹤 compiler-cli 的增量編譯如何為 main.ts、m1.ts、m2.ts 和 src/lib/types.ts 判定 affectedFiles。將 console.log(1) 改為 console.log(2) 後，types.ts 不再包含在 affectedFiles 中，即表示完成。
