Upgrade Firebase higher than 18.5.0

Package.json

"@react-native-firebase/analytics": "18.5.0",
"@react-native-firebase/app": "18.5.0",
"@react-native-firebase/crashlytics": "18.5.0",
"@react-native-firebase/dynamic-links": "18.5.0",
"@react-native-firebase/firestore": "18.5.0",
"@react-native-firebase/messaging": "18.5.0",

The Swift pod `FirebaseCoreInternal` depends upon `GoogleUtilities`, which does not define module

pod 'GoogleUtilities', :modular_headers => true

The Swift pod `FirebaseSessions` depends upon `FirebaseCore`, …

pod 'FirebaseCore', :modular_headers => true
pod 'FirebaseCoreExtension', :modular_headers => true
pod 'FirebaseInstallations', :modular_headers => true
pod 'GoogleDataTransport', :modular_headers => true
pod 'nanopb', :modular_headers => true

Reorder Embed Foundation Extensions

Swift class extensions and categories on Swift classes are not allowed to have +load methods

objc[80308]: Swift class extensions and categories on Swift classes are not allowed to have +load methods

Replace in VisionCamera

@interface objc_name (FrameProcessorPlugin)
...
+(void)load

with

@interface objc_name (FrameProcessorPlugin) <FrameProcessorPluginBase>
...
__attribute__((constructor)) static void VISION_CONCAT(initialize_, objc_name)() \
