NaCl: Remove use of nacl::DescWrapper from nacl_ipc_adapter.cc

NaCl: Remove use of nacl::DescWrapper from nacl_ipc_adapter.cc

NaCl's DescWrapper class is deprecated and we don't want Chromium-side
code to be using it.  The main reason for using it before was the
Import*() methods, but we've added C constructors to replace these.

So that RewrittenMessage unrefs NaClDescs automatically, we add a new
wrapper class.

TEST=NaCl tests in browser_tests

DISALLOW_COPY_AND_ASSIGN. Even though it's a small, local class, it seems
worthwhile, since if one gets copied, it will do the wrong thing.
