There were some remaining headers that were not guarded with _LIBCPP_HAS_LOCALIZATION, leading to errors when trying to use modules on platforms that don't support localization (since all the headers get pulled in when building the 'std' module). This patch brings these headers in line with what we do for every other header that depends on localization. This patch also requires including <picolibc.h> from <__configuration/platform.h> in order to define _NEWLIB_VERSION. In the long term, we should use a better approach for doing that, such as defining a macro in the __config_site header.
