Ixeris

This version consists of some internal refactors that aim to significantly enhance mod compatibility.

• Implemented a new system for ensuring the thread safety of GLFW callbacks. Compared with the old system that wraps and schedules every callback, this is compatible with more mods
• Refactored the cache system to be more reliable
• Fixed segmentation fault caused by standard cursor cache
• Fixed monitor cache
• Added cache for window content scale, window size, framebuffer size, and window focused & iconified state to improve performance
• Slightly optimized memory usage
