Add types for the remaining optimizers. (#31130)
Summary:
**Patch Description**
Round out the rest of the optimizer types in torch.optim by creating the stubs for the rest of them.
**Testing**:
I ran mypy looking for just errors in that optim folder. There's no *new* mypy errors created.
```
$ mypy torch/optim | grep optim
$ git checkout master; mypy torch/optim | wc -l
968
$ git checkout typeoptims; mypy torch/optim | wc -l
968
```
