actual Linux launch support

The "Steam (Auto)" launch method should ideally work in all scenarios,
ideally! Obviously, I can't and haven't tested in every environment, but
I've attempted to make sure it functions.

Launching Vanilla and Northstar works just fine, custom launch arguments
also work just fine, it works with normal Steam, Flatpak Steam, and as a
fallback with the Steam Browser Protocol (`steam://`)

There's also the option to set your own/custom launch command for both
the Vanilla and Northstar launch options. How well they work will of
course depend on what the user set them to.

"Steam (Auto)" attempts to pick the right Steam launch method depending
on what's available, if the Steam executable can be found, it'll use
"Steam (Executable)", if it cant and Flatpak is found on top of an
install of Steam through Flatpak, then "Steam (Flatpak)" is used, if all
of that fails, then we attempt to use "Steam (Protocol)"

Some toasts will be shown if you attempt to run the game with either
"Steam (Executable)" or "Steam (Flatpak)" and they cant find the
game/Steam. This isn't an issue with "Steam (Auto)"
