[BUG]: cuda::std::extents::extent does not work in constexpr context if there is at least one dynamic_extent present

### Is this a duplicate?

- [X] I confirmed there appear to be no [duplicate issues](https://github.com/NVIDIA/cccl/issues) for this bug and that I agree to the [Code of Conduct](CODE_OF_CONDUCT.md)

### Type of Bug

Compile-time Error

### Component

libcu++

### Describe the bug

It's not possible to use extents::extent in for eg. static_assert even when statically known extent is queried if extents contain at least one dynamic_extent. If all extents are statically known, then extent works in constexpr contexts.

### Expected behavior

Both static asserts from the godbolt link should compile correctly, presence of dynamic_extent should not affect the ability to query statically known extents at compile time.
