    libstdc++: Make debug containers prefer copy ctor to base ctor (PR 90102)

    When given a type which can convert to any container-like type, the
    C(const C&) copy constructor and C(const C::_Base&) converting
    constructor are ambiguous. This change replaces the converting
    constructor's parameter with a reference_wrapper-like type so that
    calling that constructor requires an additional user-defined conversion.
    This gives it a lower rank than the copy constructor, avoiding the
    ambiguity.

    While testing this change I discovered that __gnu_debug::forward_list
    doesn't have a convering constructor from the std::forward_list base, so
    this adds it.

    We should probably consider whether the converting constructors should
    be 'explicit' but I'm not changing that now.

    libstdc++-v3/ChangeLog:
