Qt 6 port of the MultiEffectqt6
Port the Qt Quick MultiEffect to Qt 6. The API remains fully compatible,
while the implementation changes to use Qt RHI. Instead of creating the
optimal shader at run time, contains 30+ pre-baked shaders and the most
suitable ones are selected based on which effects user enables.
The shaders contain OpenGL, OpenGL ES, Vulkan, Direct 3D and Metal
versions. Includes compile.bat to regenerate the qsb shaders.
Task-number: QTBUG-88645
