hints: Remove SDL_HINT_DEBUG_LOGGING.

Browse Source 
This now just needs generic debug-level logging enabled, for example:

```bash
SDL_LOGGING=debug ./test/testsprite
```

Fixes #13425.

/**
* A variable controlling whether SDL logs some debug information.
*
* The variable can be set to the following values:
*
* - "0": SDL debug information will not be logged. (default)
* - "1": SDL debug information will be logged.
*
* This is generally meant to be used as an environment variable to let
* end-users report what subsystems were chosen on their system, perhaps what
* sort of hardware they are running on, etc, to aid in debugging. Logged
* information is sent through SDL_Log(), which means by default they appear
* on stdout on most platforms, or maybe OutputDebugString() on Windows, and
* can be funneled by the app with SDL_SetLogOutputFunction(), etc.
*
* The specific output might change between SDL versions; more information
* might be deemed useful in the future.
*
* This hint can be set anytime, but the specific logs are generated during
* subsystem init.
*
* \since This hint is available since SDL 3.4.0.
