[JIT] remove specialized list ops (#34520)

Summary:
Now that lists are no longer specialized, we can register only one operator for list ops that are generic to their element type.
This PR reorgs lists into three sets of ops:
- CREATE_GENERIC_LIST_OPS
- CREATE_SPECIALIZED_LIST_OPS
- CREATE_COMPARATOR_LIST_OPS_SPECIALIZED (we didn't bind certain specialized ops to Tensor)

This is important to land quickly because mobile is finalizing its bytecode soon, after which we could not remove these ops.
