Update documentation of implementation-defined library features

	* doc/xml/manual/status_cxx2011.xml: Use <variablelist> for
	documentation of implementation-defined types for [thread.req.native].
	* doc/xml/manual/status_cxx2017.xml: Update documentation of
	implementation-defined strings for [variant.bad.access]. Fix typo in
	documentation of implementation-defined support for [fs.conform.9945].
	* doc/html/*: Regenerate.
