Goner Setup + Tutorial first pass

Closes #697

See merge request KartKrew/Kart!1692

- Helper functions for eased X/Y
- Don't jump Metal's camera around when doing things rapidly
- Don't have ctrl alt del open mouths when not on the main Goner menu itself

- Plays unconditionally, even while mid-game
- ...except on the Goner Setup, per direct request

- Imply passage of time when returning from Tutorial to Outro by resetting all the background variables
- Add an additive layer to the Options cogs, so they show up over an extremely dark background
- Metal Sonic will not focus on Tails/Eggman until video is restored
- Don't draw the Miles Electric transparent unless it's completely in its upright position

- Checks for whether a Gamepad is connected
    - If yes, says you can use "your Gamepad"
    - If no, says you can use "Enter, ESC, and the Arrow Keys"
- Show ENTER and ESC on any Message prompt (instead of A/B/X) if no Gamepad is connected
    - Add M_DrawMediocreKeyboardKey, a genericisation of the previous entry in the series' Time Attack HUD

M_DrawMenuTyping: Update informational text, since you can no longer automatically switch between Virtual Keyboard and standard typing while the dialog is open.

- More clinical wording
- Guarantee never auto-show when Playing()

- Assign poses for Outro and GDQ Passwords
- Flicker camera when showing visuals after using a GDQ Password

- Force to play when selecting "START GAME" from the Goner Setup
- Make far shorter on the First Boot, obscuring the extended Kart Krew vroom, to prevent it playing identically twice
- Prevent skipping the intro at all if Ring Cup hasn't been unlocked
    - Both for the shortened initial startup and the START GAME first encounter
- It already clears dirmenu if relevant, don't do that twice

- Eggman's mouth moves
- Smooth camera movement
- Smooth Miles Electric movement
- Less fragile/instant blinking

Tails and Eggman talking to each other/Metal Sonic/the player.

Fix GLENCORE memory leak, re-enable

- Hook into M_PlayMenuJam, to reduce bespoke behaviour
- Use the finalised track string
- Play on the Sound Options menu
Also, use MAIN_Goner as reference for the password field's presence, because I lost like 30 minutes to a related bug

Fix language standard compliance

readskincolor: sizeof is compile-time evaluated, literally why do we need to run the allocator for this

We don't need to dedicate time to allocation - we know the upper bound to this array size, and it's not very much at all.

Switch from CPM to vcpkg
