Allow launching a profile with command line arguments (--launch <uuid>)

[Sulfrix]

Some users may want to skip using the launcher and have a shortcut that directly launches YARG. This PR allows the YARC Launcher to read command line arguments and open the game immediately.

Note that this is not the implementation for a "Create Shortcut" button or something similar, the shortcut shown in the example video was created manually. Nevertheless, it should make creating shortcuts fairly simple.

Some implementation details:

• This PR uses the "clap" crate for argument parsing. It includes --help and --version arguments by default. I'm not sure if the extra dependency is wanted, but it seems like the easiest way to include argument parsing.
• Since profile information doesn't seem to be accessible from the Rust backend, it doesn't directly launch the game. It stores the launch parameter, exposing it to the frontend, which later accesses it (right after profile information is initialized, in the loading screen component) and then launches it. Preferably, the backend would completely skip opening the frontend at all and would truly launch the game directly, but this is the easiest way I found to add this system to the launcher without moving any profile logic to the backend.
• The launch logic was copied from the "ProfileState" code directly into the loading screen because useProfileState uses hooks, which makes it inaccessible during an effect. However, I could be wrong and there may be a way to directly use the launch() method without duplicating the logic.
