libcamera: base: span: Explicitly default copy assignment

The `dynamic_extent` specialization is currently not trivially copyable
unlike its standard counterpart, `std::span`. This is because the copy
assignment operator is user-defined. Explicitly default it just like
it is done in the main template definition.
