SkQP: Cloud Scripts

- tools/skqp/generate_gn_args.sh - single script to generate
    configuration used to build SkQP.
  - tools/skqp/make_model.sh - script to execute make_gmkb.go and put
    the results in the correct place.
  - tools/skqp/{up,down}load_directory_contents.sh - scripts to move
    large assets into the cloud and retrieve them.
  - tools/skqp/gm_runner.cpp - treat missing text files as empty.
  - tools/skqp/make_apk.sh - make use of generate_gn_args.sh.
  - tools/skqp/make_{model,known_tests}.sh - better error handling,
    and also stop calling `git add`.
