PropertyBinding: fix map property binding regression introduced in #24537

Related issue:

• PropertyBinding: Allow map as target object. #24537

Description

The change to allow map as target object unfortunately broke traversal for general objects, such as what KHR_animation_pointer (#24108) requires for animating materials – while NodeName.map.repeat works it broke MaterialName.map.repeat for animated materials since a material doesn't have a .material property...

This PR fixes that by checking if the animated object already has a map property, because then the indirection to .material.map isn't needed.

Note

My preferred way to fix this would be a broader change in bind() to ensure that when an objectName is found in targetObject that is always used – but that's a separate discussion I think:

if ( objectName && objectName in targetObject ) {

	targetObject = targetObject[ objectName ];

} else if ( objectName ) {

	let objectIndex = parsedPath.objectIndex;
        .... existing special cases ...
