libstdc++: Fix constraint recursion in std::expected's operator== [PR119714]
This std::expected friend operator== is prone to constraint recursion
after CWG 2369 for the same reason as basic_const_iterator's comparison
operators were before the r15-7757-g4342c50ca84ae5 workaround. This
patch works around the constraint recursion here in a similar manner,
by making the function parameter of type std::expected dependent in a
trivial way.

PR libstdc++/112490
libstdc++-v3/ChangeLog:
* include/std/expected (expected::operator==): Replace
non-dependent std::expected function parameter with a dependent
one of type expected<_Vp, _Er> where _Vp matches _Tp.
* testsuite/20_util/expected/119714.cc: New test.
