UX guide restructure

The goal of this MR was to update the current UI guide to more of an UX guide (starting to detail when to use certain controls and patterns), and add structure to help organize the information. This initial version of the UX guide also lays down the groundwork for principles and personality. This guide is currently documenting the existing design, and will continue to be updated as the design evolves.

Remove project_title additions from builds and environments

## What does this MR do?

Removed soon-to-be un-needed project title additions from builds and environments.

**This MR depends on !5998, which introduces subnav to these pages. Without it we're just removing a useful link.**

## Are there points in the code the reviewer needs to double check?

@iamphill Is this right of me? One of these still exists in `projects/artifacts/browse`, I'm not sure whether to fix the issue with `project_title`, which already has some issues with its chevron, or just remove it as it will soon be redundant.

See merge request !7398

The AddVisibilityLevelToGroups migration introduced a visibility_level for
namespaces and specified that projects should always have a visibility level
less than or equal to their namespace. However, some invalid rows could have
been created.

This commit introduces a migration that updates the invalid rows, setting the
invalid project to have the same visibility_level as their namespaces. This
will make some projects internal or private when they would previously have
been public or internal, but this is better than silently making an internal
or private group public.

In this case comparing old_path and new_path is not enough because there
are two entires that match.
