RevoluPowered 0bd877780f FBX Importer Generation 3
Basic skin support

Various fixes

- Fixes bind mount id and mesh index
- Fixed duplicate nodes being created
- Prevented leak when instances being freed during re-import.
- Improved camera and light transform import
- skeleton handling and technical debt removal
- ASSIMP: bone nodes were unlinked from bones by this code
- bone_add working can distinguish between armatutes
- Updated transform to be the correct offset
- Added safety for state.root node errors
- Fixed memory leak with leaf bones
- Implemented children re-parenting for mesh template
- import_animation fixes to basic skeleton data
- Adds some more debug messages
- Fixed Godot import segfault
- Fix build failing on mono
- Clear resources we use which are no longer required after import
- Fixed bone duplication issue
- Working skeleton_bone_map which can lookup armatures properly now.
- Fixed stack being used up when mesh swapped & Fixed bone ID

Additional notes:
We use a mesh template which is a fake node to instance the initial
mesh nodes . This is to ensure the entire tree can be built.

We replace mesh node templates with the real mesh after the
skeleton is available, since this makes it ensure that the fully
built skeleton exists with all bones, all nodes, etc.

The bone stack is a stack which pops when it finds bones,
this overcomes duplicate bones with the same names.

FBX has lots of these because animation armature has bone names like bone001
and another armature will also have bone001
Fixed errors in node path assignment

Simple explanation:
- Every mesh uses a node from the stack
- Node stack was empties before completed
- Every time node not found, stack must be rebuilt to maintain correct armature order :)

Additional fixes:
- Fixes destructor in assimp
- Implements aiNode* mArmature in bone data
- Implements aiNode* mParent in bone data
- Fixes parent ID on bones.

Implemented skeleton assignment in generate_mesh_indicies

This is the only place we can safely do a lookup for the skeleton for the mesh.h
I used a pointer reference so we can pass this back out, since the skeleton assignment happens inside the function.

Added mesh re-parenting to the armature node this is a permanent feature and must be enforced, just like GLTF2 specification.

Fixed import_animation spawning tracks per skin
