Currently MetalRT interpolates transformation matrix on per-element basis which leads to issues like #135659. This change adds implementation of for decomposed (Scale/Rotate/Translate) motion interpolation, matching behavior of BVH2 and other HW-RT. This requires macOS 15 and Xcode 16 in order to use this interpolation. On older platforms and compilers old interpolation is used. Currently there is no changes on the user (by default) and it is only available via CYCLES_METALRT_PCMI environment variable. This is because there are some issues with complex motion paths that need to be looked into. Having code available makes it easier to do further debugging.
