[roll] Roll fuchsia [svc] Remove obsolete functionality at NEXT

Unfortunately these symbols were never removed after API level 10, so
the symbols for these still exist in `libsvc.so` at all API levels since
then. To prevent them from being a part of future SDK releases, we use
an API level guard to prevent them from being generated entirely.

Test: No functional change.
