Vulkan: Improve RenderTargetVk's getImage interface Prior to this change, RenderTargetVk had getImage() and getImageForWrite(). This change introduces getImageForCopy() and renames getImage() to getImageForRenderPass(). Currently, all three functions do the same thing. However, with upcoming changes the semantics will be different: - getImageForRenderPass(): This is the image used as the non-resolve attachment. When resolve attachments are introduced, there will be a corresponding getResolveImageForRenderPass(). - getImageForCopy(): When GL_EXT_multisampled_render_to_texture is implemented, this will return the image that owns the data. - getImageForWrite(): Similar to getImageForCopy(), but should set mContentDefined. This is currently missing, and is a bug that will be resolved in a follow up. This split change gets the mechanical rename out of the way to make future changes simpler.
