Remove template field from debug render tree

The `name` field already identifies components in the render tree (now
reliably, thanks to the object-based scope bag). The `template` field
(module name of the backing template) adds no useful information beyond
what `name` provides, so remove it from `RenderNode`,
`CapturedRenderNode`, and all producers/consumers.
