Rodrigo Girão Serrão 2a810f8c87 Implement border (sub)title. (#2064)
* Add Widget.border_title and border_subtitle.

Related issues: #1864

* Test setting border_(sub)title.

* Add border (sub)title references to StylesCache.

These internal references will make it easier for the instance of 'StylesCache' to know which border (sub)title to use, if/when needed.

* Add method to render border label.

* Add styles to align border (sub)title.

* Render border labels.

* Update styles template.

* Make new 'render_row' parameters optional.

* Add (sub)title border snapshot tests.

* Document border (sub)title and styles.

* Pass (sub)title directly as arguments.

Get rid of the watchers to make data flow easier to follow.

* Tweak example.

* Fix render_border_label.

This was wrong because border labels can be composed of multiple segments if they contain multiple styles. Additionally, we want to render a single blank space of padding around the title.

* Ensure we get no label when there's no space.

* Add tests for border label rendering.

* 'render_border_label' now returns iterable of segments.

* Add label to render_row.

* Fix calling signature in tests.

* Add padding to snapshot tests.

* Fix changelog.

* Update snapshot tests.

* Update snapshot tests.

* Border labels expand if there's no corners.

* Update CHANGELOG.md

* Fix docs.

* Remove irrelevant line.

* Fix snapshot tests.

* Don't share Console among tests.

* Simplify example in styles guide.

* Avoid expensive function call when possible.

* rewording

* positive branch first

* remove wasteful indirection

* fix changelog
