This patch adds the Metal host-side code: - Add all core host-side Metal backend files (device_impl, queue, etc) - Add MetalRT BVH setup files - Integrate with Cycles device enumeration code - Revive `path_source_replace_includes` in util/path (required for MSL compilation) This patch also includes a couple of small kernel-side fixes: - Add an implementation of `lgammaf` for Metal [Nemes, Gergő (2010), "New asymptotic expansion for the Gamma function", Archiv der Mathematik](https://users.renyi.hu/~gergonemes/) - include "work_stealing.h" inside the Metal context class because it accesses state now Ref T92212 Reviewed By: brecht Maniphest Tasks: T92212 Differential Revision: https://developer.blender.org/D13423
