Evan You 02cbbb718c perf: support only attaching slot scope ids when necessary
This is done by adding the `slotted: false` option to:

- compiler-dom
- compiler-ssr
- compiler-sfc (forwarded to template compiler)

At runtime, only slotted component will render slot fragments with
slot scope Ids. For SSR, only slotted component will add slot scope Ids
to rendered slot content. This should improve both runtime performance
and reduce SSR rendered markup size.

Note: requires SFC tooling (e.g. `vue-loader` and `vite`) to pass on
the `slotted` option from the SFC descriptoer to the `compileTemplate`
call.
