Remove android game activity from default (#23708)

android handle only one activity, either game or native. To use native,
the default could now be used, but all other android need to add the
game activity.

# Objective

android native activities should be able to use the default

## Solution

remove android-game-activity from default

## Testing

created a default app for android native activity with default

## Important

Will be a breaking change for apps using android-game-activity.

+
+Bevy previously had `"android-game-activity"` as part of its default features. Users that wanted to use "android-native-activity" instead, had to disable `default-features` and define all features + "android-native-activity" explicitly since they can't have both activity features at once.
+
+Now both activities are not part of the default features but need to be added explicitly.
+
+**Migration from bevy 0.18 to 0.19:**
+
+For apps using `GameActivity` you need to add the feature `"android-game-activity"` to your `Cargo.toml`:
+
+```toml
+bevy = { version = "0.19", features = ["android-game-activity"] }
+```
+
+Since apps using `NativeActivity` already define features explicitly, you don't have to necessarily make changes. If you want to use the default features instead, you can now just add the feature `"android-native-activity"` to your `Cargo.toml` instead of redefining features explicitly:
+
+```toml
+bevy = { version = "0.19", features = ["android-native-activity"] }
+```
