The new USB descriptor parsing code is a nice candidate for a fuzzer,
since it takes an arbitrary stream of bytes as input and parses it.

Separated out of CL:1513058 to make it possible to land parts
individually while the affected crate has no other significant CLs
pending. This avoids repeatedly introducing non-textual conflicts with
new code that adds `use` statements.

Add a top level fuzz directory. Other fuzz tests will be added here in
subsequent commits.
For now fuzzing must be run manually. Soon there will be a way to
extract the fuzz artifacts and upload them to cluster fuzz.
