add dynamic shapes support for subclasses that override size/stride (#107916)
This is mostly a minor fix on top of @soulitzer's PR https://github.com/pytorch/pytorch/pull/107839.
(1) `strides` wasn't going through the new `set_tensor_attr_with_capsule` flow
(2) The dynamic shapes overload for `_make_wrapper_subclass` currently errors when you try to use custom sizes - I removed the error
(3) added a test
I need this later because I'm adding a `__torch_dispatch__` `FunctionalTensor` wrapper subclass, that needs to support dynamic shapes, and also plumb metadata calls to its inner tensor later.
