Header: Simplified, split and re-orgranised view file(s)

- Moved "common" template partials, that are only used in layouts, to
  layouts/parts folder.
- Simplified HTML structure of header template.
- Extracted logo and links from header template to simplify.
- Added header-links-start template for easier extension/customization
  without needing to override full list of links.
  - Added test to cover usage of this.

For #4564
