glTF exporter: add a hook for user extension to change json encoding
This allows user to use no indent in json, for example
Here is an example of hook:
```
def gather_gltf_encoded_hook(self, gltf_format, sort_order, export_settings):
gltf_format.indent = None
gltf_format.separators = (',', ':')
```
