Fix RenderPass loadOp synchronization hazards.

Fix RenderPass loadOp synchronization hazards.

Fix synchronization validation errors similar to:

"vkCmdBeginRenderPass: Hazard READ_AFTER_WRITE in subpass 0 for
attachment 0 aspect color during load with loadOp
VK_ATTACHMENT_LOAD_OP_LOAD.

Access info (usage: SYNC_COLOR_ATTACHMENT_OUTPUT_COLOR_ATTACHMENT_READ,
prior_usage: SYNC_IMAGE_LAYOUT_TRANSITION, write_barriers: ....)"

VK_ATTACHMENT_LOAD_OP_LOAD requires VK_ACCESS_COLOR_ATTACHMENT_READ_BIT.

VK_ATTACHMENT_LOAD_OP_DONT_CARE and VK_ATTACHMENT_LOAD_OP_CLEAR require
VK_ACCESS_COLOR_ATTACHMENT_WRITE_BIT.
