This leads to code that is easier to understand and runs
faster thanks to GDScript's typed instructions.
The untyped declaration warning is now enabled on all projects
where type hints were added. All projects currently run without
any untyped declration warnings.
Dodge the Creeps and Squash the Creeps demos intentionally don't
use type hints to match the documentation, where type hints haven't
been adopted yet (given its beginner focus).

- Move all demo projects that don't require Forward+/Mobile-only features
to the Compatibility rendering method. This improves performance significantly
on low-end devices and ensures visuals are identical to a web export
of the demo.
- Set deadzone on all inputs to 0.2 for better gamepad usability.
- Remove reliance on `default_env.tres` to use built-in Environment
resources in the main scene instead (which follows the preview environment
workflow).
- Remove notices pointing to GDNative or VisualScript, since both were
removed in 4.0.
- Various bug fixes and usability tweaks to 10+ demos.
