feat(#162): fabric support

[mateusz1913]

Overview

closes #162

👋 this PR introduces Fabric support for MaskedView from RN >= 0.71

List of changes:

• add JS Flow spec
• make android viewmanager to conform to codegen-ed specs
• make android viewmanager extend ReactViewManager instead of ViewGroupManager (closes #218)
• add codegen-ed spec to make viewmanager work also in old arch
• use install_module_dependencies in the podspec to install deps on both new and old architectures
• add subclass of RCTViewComponentView
• use fabric implementation when RCT_NEW_ARCH_ENABLED flag is true
• set RN peerDependency to be version >= 0.71

Additionally, this PR upgrades RNTA to v3 & RN to v0.73 to make it possible to test the lib when new arch is enabled

Test Plan

1. Run yarn in the example directory
2. Test the lib on Android old arch
   • Set the newArchEnabled=false in example/android/gradle.properties
   • Run the app on Android
3. Test the lib on Android new arch
   • Run the ./gradlew clean in example/android
   • Set the newArchEnabled=true in example/android/gradle.properties
   • Run the app on Android
4. Test the lib on iOS old arch
   • Install Pods (npx pod-install)
   • Run the app on iOS
5. Test the lib on iOS new arch
   • Clean the build in XCode
   • Install Pods with RCT_NEW_ARCH_ENABLED flag (RCT_NEW_ARCH_ENABLED=1 npx pod-install)
   • Run the app on iOS
