Add Google Firebase Analytics at least to Android and iOS implementations

[theromis]

Describe the project you are working on

Need it and wrote simple plugin for android, but adding it to iOS too painful.

Describe the problem or limitation you are having in your project

Adding Google Analytics to iOS too painful.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

Just build engine with google analytics linked in.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

Just report to google events what developers want to research.

If this enhancement will not be used often, can it be worked around with a few lines of script?

Just write plugin/module.

Is there a reason why this should be core and not an add-on in the asset library?

Building addon is pretty hard to build on iOS.

Moving to discussion, as there is no concrete technical implementation provided.

https://github.com/funseek/godot-ios-firebase-analytics
here is ios firebase analytics for 3.5, code by itself pretty simple, can be easily converted to 4x
for android I have a plugin, can share it here
https://github.com/FeatureKillersGames/FirebaseAnalyticsGodotAndroidPlugin
this is plugin forked from in my android implementation

IMO, Adding any SDK is the worst idea, Godot is just a game engine, and it should make server add plugin to Godot, rather Godot add plugin to server.

Agreed, extra dependencies is not ideal, but adding any sdk for iOS real pain, just look at this part:

To generate Godot headers you need to run compilation command inside godot submodule directory.
Example:

./scripts/generate_headers.sh
run pod install. [CocoaPods](https://cocoapods.org/)

pod install
Building a .a library

./scripts/release_static_library.sh 3.5
...

maybe making iOS modules as an extra library can help?
btw: Unity have Firebase Analytics out of the box, thought godot can do the same
