Move Pytorch backend

Move pytorch backend from qibo to qiboml

We should wait for the new release of qibo in order to merge

Do you think now we can update this and merge @Simone-Bordoni? :)

I think now the tests should pass. The backend migrated here is updated with Qibo and a couple of errors have been fixed. Have a look whenever you can @BrunoLiegiBastonLiegi and imho we can merge it.

Honestly, I am not sure whether it is worth rushing this by friday. As I see it, there are still two relevant matters open:

• what to do with the tests? Do we leave them in qibo, thus creating the same ongoing problems we have with qibojit as well, or do we try to solve this once and for all, maybe splitting the tests in the different repos as we were discussing earlier in the meeting?
• The PyTorchBackend is not really working for what it's more important (the gradients) Fix pytorch gradients qibo#1450, thus we would be moving something buggy anyway

I am fine in re-discussing the testing strategy and so post-poning this to next releases. Both your comments are correct and I agree. Anyway, it is useful if we merge this here, no? (without the need of rushing for the migration)

Yes we can, I mean qiboml is quite a work in progress in any case right now and even the main is not really tested, but I am not sure what this buys us. We will need to open a new PR for the PyTorchBackend in any case as soon the gradients problem gets fixed.

Ok, fine. We can keep this open until that moment.
