renderer_vulkan: Rewrite stream buffer + other fixes

Browse Source 
* Emulate blend color and clip planes correctly

* Don't hack the depth in the vertex shader, use VK_EXT_depth_clip_control for now to set the range to -1, 1

* Rewrite the stream buffer to remove flickering problems. The new implementation doesn't try to be smart about holding memory. It divides the allocation in SCHEDULER_COMMAND_COUNT buckets and automatically switches between them based on the current slot index
