libstdc++: Export std::__basic_file::native_handle as GLIBCXX_3.4.33 [PR114692]

libstdc++: Export std::__basic_file::native_handle as GLIBCXX_3.4.33 [PR114692]

I added this new symbol in the wrong version. GLIBCXX_3.4.32 was
already used for the GCC 13.2.0 release, so the new symbol should have
been in a new GLIBCXX_3.4.33 version.

Additionally, the pattern doesn't need to use [cw] because we only ever
use __basic_file<char>, even for std::basic_filebuf<wchar_t>.

libstdc++-v3/ChangeLog:

	PR libstdc++/114692
	* config/abi/pre/gnu.ver (GLIBCXX_3.4.32): Move new exports for
	__basic_file::native_handle to ...
	(GLIBCXX_3.4.33): ... here. Adjust to not match wchar_t
	specialization, which isn't used.
	* testsuite/util/testsuite_abi.cc: Add GLIBCXX_3.4.33 and update
	latest version check.
