Add Continuous Collision Detection to Physical Bones

[eddieataberk]

Describe the project you are working on

A 3D game with physical animations

Describe the problem or limitation you are having in your project

Physical bones go through surfaces at high speeds. Currently, I'm working around that issue by creating a rig that utilizes RigidBody3D instead of Physical Bones just to use CCD.

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

Just like RigidBody3D add Continuous CD option to Physical Bones.

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

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

No.

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

This is about improving a built-in class

[eddieataberk]

Found a workaround. Calling this code to Skeleton3D enables ccd for physical bones

	for child in get_children():
		if child is PhysicalBone3D:
			PhysicsServer3D.body_set_enable_continuous_collision_detection(child.get_rid(), true)

Thanks for the proposal! Consolidating in #5291.
