Make `device_reference<T>::operator=` `const` #4740

bernhardmgruber · 2025-05-19T13:29:31Z

This is in line with device_reference being a proxy reference, where assigning to a proxy reference does not change the reference itself, but the referred object (the const is shallow).

This also makes device_ptr satisfy std::indirectly_writable.

Fixes: #4621
