Make openFile exception safe
* `openFile` could sometimes leak file descriptors if it
received an asynchronous exception (#19114, #19115). Fix this
on POSIX.
* `openFile` and more importantly `openFileBlocking` could not
be interrupted effectively during the `open` system call (#17912).
Fix this on POSIX.
* Implement `readFile'` using `withFile` to ensure the file is closed promptly on exception.
* Avoid `bracket` in `withFile`, reducing the duration of masking.
Closes #19130.
Addresses #17912, #19114, and #19115 on POSIX systems, but not
on Windows.
