Cycles: Replace own aligned allocator with system one This replaces our own implementation of aligned malloc with system calls, which depends on which operation system you're on. This is probably really minor noticeable change, but in the same time it might reduce amount of wasted memory.

Refactor: Cycles: Automated clang-tidy fixups in Cycles * Use .empty() and .data() * Use nullptr instead of 0 * No else after return * Simple class member initialization * Add override for virtual methods * Include C++ instead of C headers * Remove some unused includes * Use default constructors * Always use braces * Consistent names in definition and declaration * Change typedef to using Pull Request: https://projects.blender.org/blender/blender/pulls/132361

Cycles: Use size_t for aligned allocator Seems it got changes by accident to int during guarded allocation work, causing bad memory allocations.

Fix T53830: Cycles OpenCL debug assert on macOS, This was probably harmless besides some unnecessary memory usage due to aligning allocations too much.

Cleanup: refactor Cycles OSL texture handling This adds our own OSL texture handle, that has info for OIIO textures or our own custom texture types. A filename to handle hash map is used for lookups. This is efficient because it happens at OSL compile time, because the optimizer can figure out constant strings and replace them with texture handles.

/* Aligned new operator. */
Fix Cycles build error after recent changes We need to do aligned alloc of the services instead of globals now since the concurrent map moved there.
