Filter out ExtendPayloadWithHandlesAttached test.

The test uses RunTestClient(), like the Serialize* tests in the same
fixture, which we filter because RunTestClientAndGetExitCode doesn't yet
work on Fuchsia.

commit 9736ba78d6c5e04dbbdd993546e0bfd655e2a06d
Author: Wez <wez@chromium.org>

Implement minimal set of Mojo platform IPC primitives for Fuchsia.

Previously we were building Mojo IPC against Fuchsia's POSIX emulation
layer, in which key APIs (e.g. sendmsg/resvmsg) are not-implemented.

To implement Mojo IPC natively for Fuchsia this CL:
- Switches Mojo HandlePassingInformation to map to the Fuchsia-specific
  base::HandlesToTransferVector (see base/launch_process.h).
- Implements the embedder PlatformChannel[Handle|Pair] classes.
- Implements the Mojo system Channel class.
- Updates the Mojo system core APIs to be aware of Fuchsia handles.
- Updates the MultiprocessTestHelper to be aware of Fuchsia.

The newly-passing tests are removed from the Fuchsia test filters.

Some functionality is notably missing:
- We do not yet support passing of POSIX file-descriptors.
- Stubs out NamedPlatformHandle APIs with NOTREACHED().
- We do not yet cope with SHOULD_WAIT on write attempts, because the
  OS doesn't ever actually return that yet
  (see https://fuchsia.atlassian.net/browse/MG-894).
