GPU: Extract GPU Base Test case The draw manager test case initialized ghost, gpu and draw manager. This change splits the base test case to GPU specific and draw manager specific test case. The GPU test base test case will be used for low level GPU tests.

GPU: Enabled Metal test cases. This commit enabled the metal gpu backend test cases. These test cases will currently fail, but are by default disabled.

Vulkan: Initial Compute Shaders support This patch adds initial support for compute shaders to the vulkan backend. As the development is oriented to the test- cases we have the implementation is limited to what is used there. It has been validated that with this patch that the following test cases are running as expected - `GPUVulkanTest.gpu_shader_compute_vbo` - `GPUVulkanTest.gpu_shader_compute_ibo` - `GPUVulkanTest.gpu_shader_compute_ssbo` - `GPUVulkanTest.gpu_storage_buffer_create_update_read` - `GPUVulkanTest.gpu_shader_compute_2d` This patch includes: - Allocating VkBuffer on device. - Uploading data from CPU to VkBuffer. - Binding VkBuffer as SSBO to a compute shader. - Execute compute shader and altering VkBuffer. - Download the VkBuffer to CPU ram. - Validate that it worked. - Use device only vertex buffer as SSBO - Use device only index buffer as SSBO - Use device only image buffers GHOST API has been changed as the original design was created before we even had support for compute shaders in blender. The function `GHOST_getVulkanBackbuffer` has been separated to retrieve the command buffer without a backbuffer (`GHOST_getVulkanCommandBuffer`). In order to do correct command buffer processing we needed access to the queue owned by GHOST. This is returned as part of the `GHOST_getVulkanHandles` function. Open topics (not considered part of this patch) - Memory barriers & command buffer encoding - Indirect compute dispatching - Rest of the test cases - Data conversions when requested data format is different than on device. - GPUVulkanTest.gpu_shader_compute_1d is supported on AMD devices. NVIDIA doesn't seem to support 1d textures. Pull-request: #104518

Metal: MTLContext implementation and immediate mode rendering support. MTLContext provides functionality for command encoding, binding management and graphics device management. MTLImmediate provides simple draw enablement with dynamically encoded data. These draws utilise temporary scratch buffer memory to provide minimal bandwidth overhead during workload submission. This patch also contains empty placeholders for MTLBatch and MTLDrawList to enable testing of first pixels on-screen without failure. The Metal API also requires access to the GHOST_Context to ensure the same pre-initialized Metal GPU device is used by the viewport. Given the explicit nature of Metal, explicit control is also needed over presentation, to ensure correct work scheduling and rendering pipeline state.
