lib/fuzzing: add fuzz_ndr_X

This NDR fuzzer links with each "interface" in the IDL files to
create avsingle binary.  This tries to matches what the fuzzing
engines desire.

It started as a copy of ndrdump but very little of that remains
in place.

The fancy build rules try to avoid needing a lof of boilerplate
in the wscript_build files and ensure new fuzzers are generated
and run when new IDL is added automatically.
