The base object will inherit the property table, for every FBX object, if it doesn't exist it will be ignored.
The previous code was dangerous and not simple to understand, this makes the code simpler and should result in no leaks with PropertyTable.
Features/Fixes:
Adds ability for multiple millions of polygons to be loaded.
Fixes memory leaks with tokens
Fixes memory leaks with property table
Fixes loading some corrupt files
Fixes meshes not having a unique name to the mesh node.
Opens up loading for two more versions: 7100 and 7200, up to 2020.
Preliminary support for Cinema4D files in parser now, before this was not possible it would cause memory corruption, which is gone now.
FBXProperties not being pointers presented simpler challenges in the long run also, fixed a bunch of bugs.
We do our own image loading, threading, and memory management in Godot already,
so the only components we need from etcpak (at least as of now) are the
`Compress*` methods defined in `ProcessDxtc.cpp` and `ProcessRGB.cpp`.
So we don't need to compile or vendor the rest.
-Used a more consistent set of keywords for the shader
-Remove all harcoded entry points
-Re-wrote the GLSL shader parser, new system is more flexible. Allows any entry point organization.
-Entry point for sky shaders is now sky().
-Entry point for particle shaders is now process().
For MinGW this is tricky to do as a two-step process like it was implemented,
as `std:🧵:native_handle()` is implementation-defined and depending on
the MinGW distribution, it may or may not be a pthread handle.
With mingw-gcc as packaged in Linux distros with pthread support it worked
fine, but with llvm-mingw it was problematic.
Setting the name in the thread directly as done for Apple platforms is simpler
and works fine.

MeshInstance added as child nodes for CollisionObject debug shapes can
be invalidated while deleting the collision object (child nodes are
deleted first), which caused accesses to invalid memory in
shape_owner_remove_shape that lead to random crashes.
Also optimized accesses to shapes to avoid copy-on-write on each
iteration.
Several optimizations in the way solver islands are processed in both
2D and 3D physics:
- Use LocalVector instead of linked list to avoid cache misses (with
persistent storage based on worst case scenario)
- Remove pairs when setup fails (no valid contact) to avoid unnecessary
solving of non-colliding rigid bodies just to return immediately
