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.
