Refactoring lambdify

In my work to refactor lambdify I had come up with a solution where I would dynamically subclass the CodePrinters in lambdify to add translations from the old translation dictionaries. I was not happy with the solution and I don't think Aaron was either, we decided to keep the old import mechanism of lambdify which populated the namespace (instead of trying to generate code for the used imports which I had been trying).

So the work on refactoring lambdify has continued in #13046. And with this <https://github.com/sympy/sympy/commit/265314fa63f5a662a7a187913d51d55a852b503c> commit I hope we are close to getting the new version of lambdify out the door.

New FloatType representation

With some underlying assumptions about floating point representation (two's complement etc.) I have now a new representation of FloatType. I'm much happier with this representation and I think with it #12693 is much closer to getting merged.
