The phrase "Your page X did not have a root layout, we created Y for
you." creates a [comma
splice](https://en.wikipedia.org/wiki/Comma_splice). This PR fixes it.

When creating a root layout automatically in dev - also create a default
head file.
This PR also makes sure more cases are covered when creating root
layouts by trying to find an available dir as close to `
app/` as possible that won't affect other layouts.

Creates a root layout if it is missing in DEV when building the page in
`next-app-loader`. If the page is in a route group, the layout will be
created there. Otherwise it will create a layout directly under `/app`.
Breaks the build if a page is found that's missing a root layout.
