Live theme changes (#1497)
* Allow theme change at runtime and add hook

* Save or restore default palette on theme change

* Update aqt widget styles on theme change

* styling fixes

- drop _light_palette, as default_palette serves the same purpose
- save default platform theme, and restore it when switching away
from nightmode
- update macOS light/dark mode on theme switch
- fix unreadable menus on Windows

* update night-mode classes on theme change

This is the easy part - CSS styling that uses standard_css or our
css variables should update automatically. The main remaining issue
is JS code that sets colors based on the theme at the time it's run -
eg the graph code, and the editor.

* switch night mode value on toggle

* expose current theme via a store; switch graphs to use it

https://github.com/ankitects/anki/issues/1471#issuecomment-972402492

* start using currentTheme in editor/components

This fixes basic editing - there are still components that need updating.

* add simple xcodeproj for code completion

* add helper to get currently-active system theme on macOS

* fix setCurrentTheme not being immediately available

* live update tag color

* style().name() doesn't work on Qt5

* automatic theme switching on Windows/Mac

* currentTheme -> pageTheme

* Replace `nightModeKey` with `pageTheme`
