Vulkan: Use vkCmdClearAttachments for unmasked scissored clears Building on work by Tim Van Patten <timvp@google.com> In https://chromium-review.googlesource.com/c/angle/angle/+/3388635, not only were unmasked scissored clears made to use vkCmdClearAttachments, but also scissored clears could use loadOp=Clear. While this is potentially faster, it comes with a number of complications. This change only does the former. Unfortunately, due to a Qualcomm driver bug that forces ANGLE to avoid vkCmdClearAttachments, code simplification in the draw path cannot be made.
