Add more industrial style blocks.

We got the copper black with its bolts/rivets in the corners, why not add this to an iron variant, adding more iron blocks like what has been done with the copper block but just with different textures (ideally with the bolts/rivets). Also why not add some for Netherite block too, it is the closest texture to an industrial iron block, that too could have more textures with bolts/rivets.
