[io] Move new Windows dependency to libdart_builtin targets

The new library dependency added to File io on Windows should be
added to the libdart_builtin targets, not the downstream
executables, so that Flutter builds that use libdart_builtin
will inherit the dependency.

Follow-up to https://dart-review.googlesource.com/c/sdk/+/335940
