feat(texture API): integrate ExtendedFacing rotation

Add ExtendedFacing rotation to the texture API.
Rotatable ExtendedFacing textures can be created with:
```java
TextureFactory.builder().addIcon(IICon).extFacing().build();
```

Improve and unify internal implementation of standard oriented and glow textures.
