  Fixed shared_ptr comparisons with nullptr_t when spaceship is unavailable. (#76781)

This was causing compilation errors when attempting to compare a
`shared_ptr<T[]>` with `nullptr`, as `get()` returns `T*` rather than `T
(*)[]`. `unique_ptr` did not have this issue, but I've added tests to
make sure.
