Vulkan: Clean up robust and emulated image clears. This change consolidates image clears in multiple places into a single site in ImageHelper initialization. It adds support for appending clear image commands as well as prepend (the default). We prepend clears because image initialization happens after data upload. The Vulkan robust clear path now works like the other back-ends. The change flushed out a bug where partially uninitialized CopyTexImage was not correctly initializing a texture before triggering a full resource clear. Texture::copyImage now uses a workaround where we first init the image before clearing it. After the init we upload the new data. We'll use the appending clears path when implementing deferred clears.
