Adds a new icon to the WinUpdater and MacUpdater. Fixes issue #11074.

Ping @MayImilae to review the icon change

Code looks good, no preference on the icon tho (so my approval probably doesn't mean much)

Wasn't the plan to merge the updater into the main application?

Wasn't the plan to merge the updater into the main application?

I didn't know about that. Is anyone working on that currently? If not, we can merge this PR so the updater looks a little nicer in the meantime.

@MayImilae Just in case you're talking about my PR (#10428): it doesn't really "merge" them, it instead just puts the updater app literally inside the Dolphin app, and only on macOS. They're still technically two separate entities.

This might sound a bit rude but I would rather (re)use the main Dolphin icon than the proposed design, which looks rather odd IMHO (two different icons, with different design styles, slapped together). It would also be consistent with DolphinTool and the macOS updater too, which currently just reuses the main app icon as well...

I personally think a different icon makes sense given the fact that our updater is not a user-facing application and should not be confused for one. But it might be even better to move it somewhere less visible or something along those lines. And I also don't think the proposed design really conveys that information ("don't touch this, it's only the updater backend").

[MayImilae]

I think that moving it to a less visible location is a much better solution than changing the icon. I mean, we still can still change the icon if we want to, but it shouldn't be right next to the EXE.

As for this icon change in particular, it's... an updater icon I guess. I never got around to making an updater icon because I couldn't figure out a way to make a great updater icon that I'd want to ship. This PR doesn't achieve that either, but it is very basic and inoffensive at least, so if there is demand for changing the updater icon, it would do the job. Though honestly I think that changing the icon is not the best solution to any user confusion about the updater, moving it away from it's prominent location is.

Worth noting that many of Apple's non-user-visible apps still have icons. Examples include Dock.app and Ticket Viewer.app in /System/Library/CoreServices (at least on my old OS version, 10.9).

As such, IMO it makes sense to move the updater to a different location and adopt this icon.
