Draco fuzz coverage (#3980)
* added draco integration files
* wrote build file and Dockerfile for Draco
* added Apache 2 license header
* changed project maintainer, cleaned up draco_decoder_fuzzer, and set working directory in Dockerfile
* added a couple of fuzzers
* two more targets
* merged from upstream
* build point cloud encoding fuzzer, renamed quantization fuzzers
* added more fuzzers
* moved fuzzers and build script to https://github.com/google/draco, made the build script here execute the new one
