Patch fxes ESO shadow pass ground corruption on Arc A750. In the colour pass where the rendering corruption first appears, the depth resource was used as a "PS - Texture". Immediately afterwards there's a Barrier where it goes from VK_IMAGE_LAYOUT_DEPTH_STENCIL_READ_ONLY_OPTIMAL => VK_IMAGE_LAYOUT_DEPTH_STENCIL_ATTACHMENT_OPTIMAL immediately following that there's a Clear from vkCmdBeginRendering which appears to be a HiZ clear. Things work when using AUX_USAGE_HIZ but AUX_USAGE_HIZ_CCS_WT (XXX: and AUX_USAGE_HIZ_CCS?) doesn't work. current thinking is this is related to 14015264727 where we had to add HDC and DC flushes to CCS and MCS fast clears. Maybe HiZ clears with CCS also have similar problems? The docs don't appear to indicate that but the docs were also wrong for color clears until recently...
