This PR adds explicit compound triggers, specified by a new "nodes" property under the "trigger" property inside of the "OMI_physics_body" extension on nodes. This replaces the old way of doing compound triggers, where a node containing "OMI_physics_body" with "trigger": {} was considered a compound trigger. Now, nodes are explicitly listed in the compound trigger node. This approach was discussed in the Khronos glTF meeting.

This PR also includes some tweaks to the prose to clarify the behavior and usage of triggers.

The example file is expected to look like this after being imported into Godot (after my PR to implement this in Godot):

I reviewed
OMI_physics_body: Add explicit compound triggers instead of implicit ones.

Maybe @antpb, @lyuma and anyone interested can review and discuss approval of compound triggers for the next OMI gltf meeting since this is a substantive change.
