[libcxx] Map Windows ERROR_NETNAME_DELETED to no_such_file_or_directory (#162257)

This fixes spurious failures in
std/input.output/filesystems/fs.op.funcs/fs.op.proximate/proximate.pass.cpp
on Windows.

As part of that test, libcxx tries to open a fake network path such as
"//foo/a". Normally, this sets the error ERROR_BAD_NETPATH, which is
mapped to no_such_file_or_directory. However occasionally, it can end up
setting the error ERROR_NETNAME_DELETED instead.

Map ERROR_NETNAME_DELETED to no_such_file_or_directory just like
ERROR_BAD_NETPATH is mapped. This makes these cases be treated equally
within the create_file_status function in
src/filesystem/file_descriptor.h, causing the __weakly_canonical
function in operations.cpp to keep iterating, rather than erroring out.
