Vulkan: Enable CPU only buffers for PBOs Add support for a CPU only buffer for PBOs that serve as the destination for all host operations like MapBuffer*. This removes the latency caused by waiting for the in-flight GPU commands to be complete before handing over the buffer to the app. This change removes a ~6ms wait/sleep on the first call to MapBuffer* in each frame of Manhattan Bug: angleproject:4339 Tests: angle_end2end_tests --gtest_filter=BufferDataTest*Vulkan Change-Id: I52016b160af8a670cc30f01c05e48f699521310f Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2116874 Commit-Queue: Mohan Maiya <m.maiya@samsung.com> Reviewed-by: Tobin Ehlis <tobine@google.com>
