38c625d070 renderer: enhanced shared surface handling with mutex implementation
Introduced a dedicated mutex for each surface instance
to ensure safe sharing between the loader, renderer, and engine.

This enhancement allows for secure modification and access to bitmap data,
addressing potential concurrency issues.

Multiple Picture instances can now safely share a single loader instance,
optimizing performance.

This change builds upon the previous Loader Cache improvements:

49d26691e5 common: Revise internal loader interfaces.
We are introducing the FontLoader, which slightly differs
from the ImageLoader in terms of features. To adequately
support both, we have separated the loader functionalities
into FontLoader and ImageLoader. This allows us to optimally
adapt the LoadModule for each case.

f64ee28079 Loaders: Introduced a loader cache.
The loader cache is applied to conserve memory.

If the input data is already present in loaders,
the loader cache will promptly return the active loader.

This results in a lot of memory savings for the duplicated resources.

dfb1a7e571 webp_loader: libwebp set to be a required depend
While building on windows (MinGW) no 'libwebp' was found,
which resulted in build errors. The building process should
have been stopp	ed earlier for clarity.
