rename semantics as attributes property in primitive

[fabrobinet]

We have this:

{
    "indices": "indices_2117",
    "material": "wood",
    "primitive": "TRIANGLES",
    "semantics": {
        "NORMAL": "attribute_2124",
        "POSITION": "attribute_2122",
        "TEXCOORD_0": "attribute_2126"
     }
}

semantics qualifies the keys, it would be more appropriate to qualify the values.

So I propose this:

{
    "indices": "indices_2117",
    "material": "wood",
    "primitive": "TRIANGLES",
    "attributes": {                                
        "NORMAL": "attribute_2124",
        "POSITION": "attribute_2122",
        "TEXCOORD_0": "attribute_2126"
     }
}

Yeah I always thought this was wrong. We should change it.

Sounds like an easy one, @pjcozzi @RemiArnaud I can change it quickly if you are OK.
