This PR adds support for clearing framebuffers and scissor testing. Tweaks had to be made to VKTexture to keep track of its layout on the device. Based on the actual call the layout can switch to a more optimum layout. For example during upload of a texture the texture will be converted to a transfer destination optimized layout. When reading from the texture it will be converted to a transfer source optimized layout. The order of the attachments in the framebuffer follows the next rules - When only color attachments are there the color attachments will be placed in the slot they are defined. This way it will match the ShaderCreateInfo binding location. - When a stencil/depth attachment is added it will be placed right after the color attachments. When there isn't a color attachment it will be the first attachment. Pull Request: https://projects.blender.org/blender/blender/pulls/106044
