Improve profiler options when debugging

[RichardJECooke]

• Show the object and scene that each function belongs to. Without that we have no idea what function Godot is talking about. Ideally, show the functions in a tree structure.
• Allow sorting columns when clicking on the header, so we can see the top time-taking functions
• Don't remove the functions on every frame if they aren't called. The function list jumps around so much we can't track a single line.
