Declarations not emitted for `include`d type-only files

What happens and why it is wrong

repro repository : https://github.com/cslecours/repro-ts-rollup-issue

In the output, I am missing types that were exported. In dist I see the types/index.d.ts but not types/abc.d.ts that it depends on. It seems to be related to the allImportedFiles Set that was added by 0.23 as I see that my files are skipped.

I did attempt at a fix, but it will probably break other things.
