Create govuk-branded.html template

[lfdebrux]

What

Create lib/nunjucks/govuk-prototype-kit/layouts/govuk-branded.html, which contains contents of current app/views/layout.html.

app/views/layout.html can contain just a single line extending new layout. We may want more in there in the future but that is out of scope for this ticket.

Make sure that govuk-branded.html includes includes/stylesheets.html and includes/scripts.html, and has stylesheets, scripts, pageScripts and other convenience blocks for users.

Why

We want to move common lines in layout.html into the kit so we have more control over it and users have less to worry about when updating.
