63dd23c5 - [libc++][ranges] Implement LWG3904: `lazy_split_view::outer-iterator`'s const-converting constructor isn't setting `trailing_empty_` (#237550)

[libc++][ranges] Implement LWG3904: `lazy_split_view::outer-iterator`'s const-converting constructor isn't setting `trailing_empty_` (#237550) Copy `trailing_empty_` in `outer-iterator`'s const-converting constructor. Previously, converting an iterator that points at the trailing empty subrange (e.g. the second element of `"a,"` split by `","`) made it compare equal to `default_sentinel`, so that subrange was lost. Fixes #105276
