Call method animation tracks require explicit enablement if the node is filtered on AnimationTree

**Your Godot version:**

4.1 beta 2

**Issue description:**

I spent hours not realizing that call function tracks won't get triggered on filtered animation if they are not explicitly filtered for as well.

Issue that describes the problem I had:

https://github.com/godotengine/godot/issues/78298

The documentation does not mention anything regarding the caveats surrounding call function tracks and filtering.
