description	Update Godot GDExtension C header files and json metadata.

Run godot --version to determine the godot version:

% godot --version
4.5.1.stable.custom_build.f62fdbde1

Update godot_headers/ Files

Run make update_godot_headers_from_binary if the extension_api.json doesn't match the godot version:

...
	"header": {
		"version_major": 4,
		"version_minor": 5,
		"version_patch": 1,
		"version_status": "stable",
		"version_build": "custom_build",
		"version_full_name": "Godot Engine v4.5.1.stable.custom_build",
		"precision": "single"
	},
...

This does 2 things

1. GDExtension header file "gdextension_interface.h". This file is the base file required to implement a GDExtension.
2. Generate a JSON dump of the Godot API for GDExtension bindings named "extension_api.json" in the current folder.

Generate Go Codegen wrapping the godot_headers files

Run make generate
