Add initial libfuzzers for fm2js transpiling and XML parsing.
GN source_sets are added so that the fuzzers can be built from
//testing/libfuzzer in a Chromium checkout.
GYP targets are also added to make sure these always build properly on
our waterfall. These don't actually build the proper libfuzzers, but
build the target fuzz function with a driver main() since the actual
build process is quite complicated.
