* refactor: consolidate `diagnostics` funcs into single file
- move `IDiagnostic` and `convertDiagnostic` from `tscache` to `print-diagnostics`, then rename it to `diagnostics.ts`
- the diagnostic funcs being in `tscache` always felt like a strange place for them
- especially when `parse-tsconfig` or `print-diagnostics` would import them from `tscache`, which sounded like an unrelated file
- may want to move `diagnostics-format-host` into this file as well, as it is _only_ used in this file
- leaving as is for now, limiting this change to a smaller one
* test: add unit test for `convertDiagnostic`
- this was previously only covered in integration tests
- since unit tests don't currently touch `index` or `tscache`, and `convertDiagnostic` was previously in `tscache`
- another reason why consolidating these functions into one file made sense
* fix(diagnostics): use `formatHost.getNewLine()` instead of `\n`
- since new lines are host OS specific
- this fixes the `convertDiagnostic` test on Windows too, where it was failing
