Merge SteamFork's SimpleDeckyTDP features upstream.

[fewtarius]

We maintain a few changes downstream in SteamFork that could be useful upstream. This request proposes the following changes:

• Deprecate and remove apu-slow-limit, as it significantly restricts APU performance. It may be desirable to reintroduce as a separate TDP slider perhaps?
• Modify fast-limit to match the explicit TDP setting as that is the desired state (according to the slider).
• Apply temperature limits to reduce risk of overheating.
• Apply max-performance option to reduce stutter in some games.
• Apply GPU modes from JELOS/SteamFork.
  • Introduce "battery" mode to force the GPU into a low power state.
  • Modify default to balanced (as it is "auto" anyway).
  • Introduce "performance" to force the GPU into the highest performance state.
  • Retains range and fixed frequency modes.
  • Re-orders slider -> Battery / Balanced / Power / Range / Fixed
  • Presents device unsupported message when ranges are not available (legacy APU devices, such as Ayaneo Air and Atari VCS).

Besides a few small little nits and typos, I think this all looks good to me!

One thing we will have to do though is write a migration for all users that'd be upgrading from an older version of SDTDP.

Since the DEFAULT gpu mode was re-named to BALANCE, anyone with DEFAULT in their settings.json might encounter an error after updating.

It should be an easy fix though, I can write up a migration that will update the settings file to replace DEFAULT with BALANCE

I can add the migration really quick after getting this PR fixed up and merged.

Looks good to me! I'll followup with a migration for the DEFAULT => BALANCE, then queue up a release

Excellent!
