feat: add `cumulative_prod` specification

This PR

resolves https://github.com/data-apis/array-api/issues/598 by adding cumulative_prod to the specification for computing the cumulative product.
follows cumulative_sum in matching axis, dtype, and include_initial semantics.
as with cumulative_sum, this specification differs from NumPy in that flattening is not the default behavior. Similar to PyTorch, an axis argument is required if the input array has more than one dimension.

#797 is relevant here too.

Update: I've added a note similar to what's suggested for cumulative_sum in https://github.com/data-apis/array-api/pull/851.

As this PR has not received any objections since April 18, is consistent with cumulative_sum, and has been previously discussed during workgroup meeting, I'll go ahead and merge. Any further changes can be addressed in follow-up PRs.
