46016e63 - [libc++] Make basic_string::__erase_external_with_move noexcept (#171591)

[libc++] Make basic_string::__erase_external_with_move noexcept (#171591) `__erase_external_with_move` is in the dylib, so the compiler doesn't see the definition. Marking it `noexcept` sometimes allows clang to remove exceptions related code, improving code size slightly.
