Cycles: Add support for rendering on Intel GPUs using oneAPI This patch adds a new Cycles device with similar functionality to the existing GPU devices. Kernel compilation and runtime interaction happen via oneAPI DPC++ compiler and SYCL API. This implementation is primarly focusing on Intel® Arc™ GPUs and other future Intel GPUs. The first supported drivers are 101.1660 on Windows and 22.10.22597 on Linux. The necessary tools for compilation are: - A SYCL compiler such as oneAPI DPC++ compiler or https://github.com/intel/llvm - Intel® oneAPI Level Zero which is used for low level device queries: https://github.com/oneapi-src/level-zero - To optionally generate prebuilt graphics binaries: Intel® Graphics Compiler All are included in Linux precompiled libraries on svn: https://svn.blender.org/svnroot/bf-blender/trunk/lib The same goes for Windows precompiled binaries but for the graphics compiler, available as "Intel® Graphics Offline Compiler for OpenCL™ Code" from https://www.intel.com/content/www/us/en/developer/articles/tool/oneapi-standalone-components.html, for which path can be set as OCLOC_INSTALL_DIR. Being based on the open SYCL standard, this implementation could also be extended to run on other compatible non-Intel hardware in the future.

Cycles: use direct linking for oneAPI backend This is a minimal set of changes, allowing a lot of cleanup that can happen afterward as it allows sycl method and objects to be used outside of kernel.cpp. Reviewed By: brecht, sergey Differential Revision: https://developer.blender.org/D15397

Cycles: Metal integrator state size tuning This patch tunes the integrator state sizing for Metal (`num_concurrent_states` and `num_concurrent_busy_states`). On all GPUs architecture, we adjust the busy:total states ratio to be 1:4 which gives better rendering performance than the previous 1:16 ratio (independent of total state count). This gives a small performance uplift (e.g. 2-3% on M1 Ultra). Additionally for M2 architectures, we double the overall state size if there is available headroom. Inclusive of the first change, we can expect uplift of close to 10% in future, as this results in larger dispatch sizes and minimises work submission overheads. In order to make an accurate determination of available headroom, we defer the calculation of `num_concurrent_states` and `num_concurrent_busy_states` until the time of integrator state allocation (i.e. after all of the scene data has been allocated). We also refactor `alloc_integrator_soa` to calculate an *exact* single-state-size in a first pass, right before allocating the integrator SoA buffers in a second pass.

Cycles: set num_sort_partition_elements to 8192 for oneAPI The default value of 65536 wasn't optimal on Intel GPUs, switching to 8192 gives a 0 to 15% performance improvement depending on the scenes.
