raytracing: Initial Vulkan support

Browse source 
- Vulkan implementations in `RenderingDeviceDriverVulkan`.
- Raytracing instruction list in `RenderingDeviceGraph`.
- Functions to create acceleration structures and raytracing pipelines
  in `RenderingDevice`.
- Raygen, Miss, and ClosestHit shader stages support.
- GDScript bindings.
- Update classes documentation.
- Unimplemented placeholders for Metal and D3D12.
- Build acceleration structure command.
- Expose a shader preprocessor define.
- Align build scratch address.
- Create STB after creating the pipeline.
- Separate acceleration structure barriers.
- Use transforms in TLAS instances.
- AnyHit and Intersection stages.
- Optionally set acceleration structure build input buffer usage.
- Introduce instances buffer.
- Move scratch buffers to RenderingDevice.
- Rename AccelerationStructureGeometryBits.
- Use regular buffer creation and free routines for scratch buffer.
- Store trackers in acceleration structures.
- Bump Shader SPIR-V version to 1.4
- Add Position attribute location in blas_create.
- Encapsulate MoltenVK check in preprocessor macro.
- Split SUPPORTS_RAYTRACING for pipeline and query.
