Part of overall "improve filtering situation" (#116980) task: * Add Bicubic filtering option to strip Transform "Filter" setting. 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.
