libstdc++: Fix a few !HOSTED test regressions

libstdc++-v3/ChangeLog:

	* testsuite/20_util/to_chars/version.cc: Mark hosted-only.
	* testsuite/20_util/uses_allocator/lwg3677.cc: Ditto.
	* testsuite/20_util/weak_ptr/cons/self_move.cc: Ditto.
	* testsuite/std/ranges/adaptors/as_rvalue/1.cc: Replace usage of
	std::make_unique with a freestanding-compatible wrapper around
	unique_ptr.
	* testsuite/21_strings/basic_string_view/operations/contains/char.cc:
	Don't test for presence of __cpp_lib_string_contains on !HOSTED.
	* testsuite/21_strings/basic_string_view/operations/contains/char/2.cc:
	Ditto.
	* testsuite/std/ranges/version_c++23.cc: Don't test for presence
	of __cpp_lib_ranges in !HOSTED.
