Vulkan: Command graph linearization (Step 1). This initial prototype introduces a new feature to the Vulkan back-end that disables the deferred command recording. The intent is to have a lower CPU overhead during submission calls which currently walk a DAG. The feature is not complete. Currently it only passes the ANGLE SimpleOperationTests. Moreover it is extremely simple and only allows use of one command buffer at a time. In the future we'll allow open command buffers for recording outside and inside render pass commands at the same time. We'll also support collapsing RenderPasses together for some use cases. Currently the prototype only passes "SimpleOperationTest". There are quite a few unimplemented features like queries, XFB, etc. Bug: angleproject:4029 Change-Id: I82760986683f55e37ac4ea559de6f4cffb6ef84e Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/1953485 Commit-Queue: Jamie Madill <jmadill@chromium.org> Reviewed-by: Tobin Ehlis <tobine@google.com>
