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.

How to Build & Run on iOS (Step-by-Step)

If you are new to iOS development or running this project for the first time, follow these steps on a Mac with Xcode installed:

1. Checkout the branch

git fetch origin
git checkout feat/experimental-kmp-module

2. Configure your local API Key

Create a file named secrets.properties in the root directory of the repository (if you don't already have one) and paste your Google Maps API key inside:

MAPS_API_KEY="YOUR_GOOGLE_MAPS_API_KEY"

3. Generate the Xcode Project & Install Dependencies

Navigate to the iosApp directory, generate the project files, and run CocoaPods to fetch dependencies:

cd iosApp
ruby create_project.rb
pod install

4. Open the Workspace in Xcode

Inside the iosApp folder, open the generated .xcworkspace file (do not open the .xcodeproj file):

open iosApp.xcworkspace

5. Run the App

• In Xcode's top toolbar, set the active scheme dropdown to iosApp (instead of maps_compose_multiplatform).
• Select any iOS Simulator (e.g. iPhone 16 or iPhone 17 Pro) in the device dropdown.
• Click the Play button (or press Cmd + R) to compile, inject the secrets, and run!
