libstdc++: Fix exports for IEEE128 versions of __try_use_facet [PR108327]

The new symbols need to be exported, as well as some of the
std::locale::facet::id globals, which are not new but were presumably
not needed by any inline functions before now.

libstdc++-v3/ChangeLog:

	PR libstdc++/108327
	* config/os/gnu-linux/ldbl-extra.ver (GLIBCXX_LDBL_3.4.31):
	Export __try_use_facet specializations for facets in namespace
	__gnu_cxx_ldbl128.
	* config/os/gnu-linux/ldbl-ieee128-extra.ver
	(GLIBCXX_IEEE128_3.4.31): Likewise for facets in namespace
	__gnu_cxx_ieee128.
	* testsuite/util/testsuite_abi.cc: Add to lists of known and
	latest versions.
