Rename `YaruCompactLayout`?

[jpnurmi]

While we still have a chance to land breaking changes before 2.0, it would be nice if YaruCompactLayout had a name that:

• sounds like a counterpart to YaruMasterDetailPage
• sounds like a natural use-case for YaruPageController
• hints that it's based on YaruNavigationRail (and possibly YaruBottomNavigationBar)
• doesn't sound like an internal helper class like YaruMasterDetailPage's YaruPortraitLayout and YaruLandscapeLayout

I wish YaruCompactLayout would be named something like YaruNavigationPage to be consistent with YaruMasterDetailPage and YaruNavigationRail but it would break the software app once again... :thinking:

• YaruNavigationPage
• YaruNavigation(Page)Theme
• YaruNavigationRail
• YaruNavigation(Rail)Item
• YaruNavigationBar
• ...?

Personally, I think that YaruNavigationPage sounds good. But what is the problem with the software app?

I didn't buy my own proposal earlier because it didn't feel like a big enough improvement to justify the break. I decided to bring it up again now that we have YaruPageController in the pipeline.

Also, I'm starting to feel embarrassed for breaking all the apps again and again but if Frederik says it's ok... :see_no_evil:
