- VSE: add Cubic Mitchell filtering, rename previous cubic to Cubic BSpline
Part of overall "improve filtering situation" (#116980) task:
Add "Cubic Mitchell" filtering option to VSE strips. This is a cubic (4x4) filter that generally looks better than bilinear, while not blurring the image as much as the Cubic BSpline filter that exists elsewhere within Blender. It is also default in many other apps.
Rename the (very recently added) VSE Bicubic filter option to Cubic BSpline.

Previously this option only existed in Transform Effect "Interpolation" setting. - With this addition, it feels like the transform effect could possibly be marked as legacy/deprecated, since the regular Transform that is on all strips can do everything that Transform Effect did? * Speed up bicubic filtering (used now in VSE, but also in CPU Compositor, image paint, etc.) by slightly simplifying the code and using some SIMD. Upscaling 96x54 image to 3840x2160 resolution, using Bicubic filtering: - Windows (VS2022, Ryzen 5950X): 35.5ms -> 15.1ms - Mac (clang 15, M1 Max): 29.6ms -> 24.4ms * Add gtest coverage for bicubic functionality.
