Feature: 2D Space Shooter UI Pass using UI Toolkit

[jilfranco-unity]

Description:

This PR contains an overhaul of the UI for the 2D Space Shooter Bitesize Sample--the old GUI UI has been replaced with new and improved UI Toolkit UI!

Overall features include:

• New visuals for buttons, input fields, player UI, and power up labels all created and implemented using UI toolkit runtime UI
• More feedback provided to user in Main Menu UI (connection status, field input validity)

Plus the removal of outdated GUI UI!

There's a known issue for an error that's thrown with UI Toolkit also, so please disregard that

Here's a before an after of the visuals

Most definitely an improvement.

I am getting cartoony/comic sans style feels from the UI buttons in the top left.
However, I don't get the same feels for the player UI and pick-ups UI - are the fonts the same?

Definitely clear and readable.
Not a matching style in my opinion.

Maybe you could try a sci-fi stylised font or present us with a few options?

Should we be able to see the name, hp, and energy of other player characters?

That is intentional, yes! You can destroy other players so it's useful to be able to see their name and resources

Thank you! :)

The font is the same for the whole game--player, power ups, menu elements

Definitely clear and readable. Not a matching style in my opinion.

(editing this comment after some reflection on the roadmap timeline) I'm not sure there's enough time to work on a full reiteration of the UI, but I can definitely try some new fonts--that might be enough to give it more of a sci-fi feel!

Here is an update to the UI! Reused some of our assets to go for more of a sci fi feel, as well as to increase cohesion between the in game background visuals and UI visuals!
