build: Update nativefiledialog and keep dialogs on top (#1771)

This PR updates the nativefiledialog submodule and uses its new feature
to set the ImHex main window as the parent of the dialog window. This
ensures that the dialog stays on top of the main window. This is
currently supported by NFDe on Windows, macOS, and Linux/X11.
Linux/Wayland behaves as it did previously due to limitations in NFDe.

Note that macOS file dialogs have already been parented properly as NFDe
previously used the key window (the window currently receiving keyboard
events) on macOS. However, it's probably better to do the correct thing
and pass the main window to NFDe even on macOS.

### Problem description
The file dialog go behind the main window if the main window is clicked
while the file dialog is open.

### Implementation description
Update nativefiledialog and pass the `GLFWwindow*` of the main window to
the library function.

### Screenshots

### Additional things
I have tested this on Windows and Linux/X11, but did not test this on
macOS. It would be ideal if someone can help with this. (But as far as
NFDe is concerned, macOS `NSWindow*` handles have been tested (with
SDL2) and works.)
