feat: unify native map views into single LuggMapView host

[lodev09]

Summary

Replace separate LuggGoogleMapView and LuggAppleMapView Fabric components with a single LuggMapView that delegates to provider-specific content classes (GoogleMapProvider, AppleMapProvider) via a shared MapProvider protocol.

Architecture

• Host view (LuggMapView) — owns Fabric lifecycle (props, commands, child mounting, events)
• Provider classes (GoogleMapProvider, AppleMapProvider) — plain objects managing the actual map view inside LuggMapWrapperView
• iOS host selects provider based on provider prop; Android always uses Google

Changes

• Unified LuggMapViewNativeComponent spec with provider prop
• iOS: MapProvider/MapProviderDelegate protocol in ios/core/
• iOS: GoogleMapProvider and AppleMapProvider content classes in ios/core/
• iOS: LuggMapView host view selects provider based on prop
• Android: GoogleMapProvider extracted to core/
• Android: LuggMapView as thin host delegating to provider
• Removed old LuggGoogleMapView/LuggAppleMapView native components

Type of Change

• Breaking change

Test Plan

• Build iOS example with both apple and google providers
• Build Android example
• Verify camera events, commands (moveCamera, fitCoordinates), markers, polylines

Checklist

• I tested on iOS
• I tested on Android
• I tested on Web
• I updated the documentation (if needed)
