[Theme] Add scheme-variant asset resolution (#7275)

* Add scheme-variant theme asset resolution (#7209-1)

ThemeManager::assetPath() and schemeVariantPath() resolve a theme asset to its scheme-variant file (prefix-light/dark.png) with fallback to the plain asset, and themePixmap()/loadBrush()/loadExtraBrush() use them. CSS files load style-dark.css or style-light.css when present. Home widget re-resolves its background on theme change.

Link pixel_map_generator.cpp into the oracle target, which needs Qt6::Xml for QDomDocument.

* Fix clang-format wrap of theme format probe lists
