feat: Add interactive KMP maps demos to iOS app & upgrade Google Maps SDK to 10.14.0

[kikoso]

Description

This PR implements rich, interactive map samples in the iOS demo app (iosApp) similar to the Android app, while extending the multiplatform :maps-compose-multiplatform library API to support a broad set of configurations and upgrading the Google Maps SDK for iOS dependency to version 10.14.0.0.

Key Changes

1. Interactive Demos List on iOS:
   • Organizes iOS samples into a structured, native UITableView with sections:
     • Map Types: Normal Map (San Francisco), Satellite Map (Grand Canyon), Hybrid Map (New York City), Terrain Map (Mount Everest).
     • Markers & Pins: Single Marker (Golden Gate Bridge), Multiple Markers (London Demos), Custom Snippet Marker (Tokyo Center).
     • Map Gestures & Controls: Gestures Enabled, Gestures Disabled (Rome - static map), and Show My Location Button.
2. KMP Library Upgrades:
   • Extended the shared GoogleMap composable and GoogleMapViewController to support MapType, MapMarker lists (multiple pins), location tracking, and gesture settings.
   • Bypassed strict plist checks inside the compose UI controller.
3. Google Maps SDK Upgrade to 10.14.0.0:
   • Upgraded the dependency version and bumped the iOS deployment target to 16.0 across the KMP module, Podfile, and project settings (as required by Google Maps v10+).
4. Secure Secrets Management:
   • Added a dynamic Populate Secrets build phase in the Xcode project to load the API key from local git-ignored secrets.properties into DeveloperSecrets.swift. Both files are excluded from Git to prevent security leaks.
