Fixes associations for `.iso`, where many apps define `application/x-cd-image` instead of `application/vnd.efi.iso`.
Popsicle and GNOME Disks will now appear as exact matches for opening `.iso` files with this change.
- Fix empty files getting `application/x-zerosize` as their mime types
- May be tested by creating an empty `test.cpp` file
- Fix the wrong app being selected as a default if that app was set as
default for another mime type
- Include video players (such as cosmic-player) as suggested apps for
audio files
- Do the same for text-based mime types so that cosmic-edit will be
displayed as a suggestion for `.cpp` files
- Allow related apps to be selected in the Open With dropdown in the
properties context drawer.

This replaces the up/down arrow glyphs in the context menu for sort
direction with actual sort icons.
This way the icon is not dependent on the user's system font. For
example "Adwaita Sans" contains the up arrow but not the down arrow,
which means the arrow changes shape (depending on the chosen fallback
font) when you switch direction.

I took the liberty to move the icon from the end of the word to the left
side and also preserve an empty space when it's not drawn. It may need
UX approval.

- instead of loading app icons, creates `icon()` and lazy load when
needed
- takes user Added Association into account instead of just relying on
the desktop files "no display".
I also changed `is_default`'s ordering from `SecCst` to `Relaxed`. Let
me know if that's wrong, but from what I see it's not necessary in this
case, `Relaxed` is fine.
