Update the path in d.ts file if declaration dir/outDir is set in project with project references

Fixes #26036

I don't think this isn't a change we should make, and the reporting user is somewhat wrong here by our typical philosophy. We don't rewrite paths in .d.ts emit (beyond making them root-relative in bundle emit) - what's incorrect was referring to the input src folder at all. declarationDir and outDir have never played well with relative imports to files not in the emit, and project reference files aren't special in this regard. Our candidate advice in these cases has always been to use relative imports only for things actually within your current unit of compilation, or to ensure that your output file structure closely mirrors your input file structure, because we won't rewrite the paths for you.

See #18972 #18951 and #16640. I don't think references meaningfully changes anything here from paths or outDir before it.

@weswigham thank you. Will update the resolution part instead then.
