GPv3: Python API: Add function to get current frame on a layer

Browse Source 
This adds the `layer.current_frame()` function which will get the frame
at the current scene time on this layer.

In the lagacy API this was the property `layer.active_frame`. Since we don't cache the visible
frame anymore, we use the current context to get the current scene time.
