Zachary Anderson 7fd15110fe [dart:io] chdir, getcwd when in a namespace
This change does a couple things:
- When there is a non-default namespace, on Linux, Android, and Fuchsia
  the current working directory is per-Isolate.
- On Fuchsia, it caches the fd from fdio_ns_t instead of recomputing it
  on every fs access.
