libstdc++: Fix availability of std::erase_if(std::flat_foo) [PR119427]

These std::erase_if overloads were wrongly implemented as hidden
friends, visible only via ADL, so erase_if(x) would work but not
std::erase_if(x).

	PR libstdc++/119427

libstdc++-v3/ChangeLog:

	* include/std/flat_map (_Flat_map_impl::erase_if): Replace
	this hidden friend with ...
	(_Flat_map_impl::_M_erase_if): ... this member function.
	(flat_map): Export _Flat_map_impl::_M_erase_if.
	(erase_if(flat_map)): Define.
	(flat_multimap): Export _Flat_map_impl::_M_erase_if.
	(erase_if(flat_multimap)): Define.
	* include/std/flat_set (_Flat_set_impl::erase_if): Replace
	with ...
	(_Flat_set_impl::_M_erase_if): ... this member function.
	(flat_set): Export _Flat_set_impl::_M_erase_if.
	(erase_if(flat_set)): Define.
	(flat_multiset): Export _Flat_set_impl::_M_erase_if.
	(erase_if(flat_multiset)): Define.
	* testsuite/23_containers/flat_map/1.cc (test07): New test.
	* testsuite/23_containers/flat_multimap/1.cc (test07): New test.
	* testsuite/23_containers/flat_multiset/1.cc (test09): New test.
