Moved ZBCManager to `video_core/zbc_manager.cpp/h` for modularity. Added
`gl_zbc_clear.cpp/h` for efficient OpenGL color, depth, and stencil clears.
Updated `RasterizerOpenGL::Clear` to use ZBC with fallback. Added stencil
type validation. Fixed color mask and logging. Updated `CMakeLists.txt`.
Enhances performance and code organization.

ZBC (Zero Bandwidth Clear) allows the GPU to perform efficient memory
clearing operations without requiring CPU bandwidth by storing clear
values in a dedicated table that can be referenced during rendering.
This implementation provides the foundation for zero-bandwidth clear
operations, allowing the GPU to efficiently clear color and depth
buffers using pre-defined values stored in the ZBC table.

- This adds implementations for ioctl command 0x13 in both Ioctl1 and Ioctl3 functions, allowing newer titles like Super Mario Party Jamboree to boot by properly handling this command with a NotImplemented response rather than failing.
