EEVEE can bind layers of a texture that is also used as an attachment. When binding the image layout of these specific layers can be different that the image layout of the whole image. This fixes the known synchronization issues inside EEVEE. wasp_bot, tree_creature and wanderer scenes can be rendered without any synchronization issue reported by the Vulkan validation layers. Design task: #124214 When beginning to render the attachments are being evaluated. If there is an arrayed texture (with multiple layers) the individual layers of that texture can be tracked during until the rendering is ended. When the same texture is bound to a shader it will be a different layer (otherwise there is a feedback loop, which isn't allowed). The bound layers will typically need a different layout the transition to the new layout is executed and recorded. When the rendering ends, the layers are transitioned back to the layout the texture is expected in. It can happen that a layer is used multiple times during the same rendering. In that case the rendering should be suspended to perform the transition. Image layout transitions are not allowed during rendering. There is one place where a layer needs to be transited multiple times that is when EEVEE wants to extract the thickness from the shadow. The thickness is stored inside the gbuffer_normal which is also used as an attachment. Eval then samples the thickness from the gbuffer_normal as a sampler. To work around this issue we suspend the rendering when a `GPU_BARRIER_SHADER_IMAGE_ACCESS` is signaled. Pull Request: https://projects.blender.org/blender/blender/pulls/124407
