* Minor refactor of theming when expressions
Avoids triggering detekt's CyclomaticComplexMethod warning because of
too many when branches, which would happen with one more theme being
added in these two locations.
In TachiyomiTheme, the Monet theme is separated because it requires
the current Compose context to function. The other themes do not and
are delegated to a Map.
* Implement requested changes
- moved themeResources out of the ThemingDelegate interface
- replaced single condition when with if expression
