Add LLVM fuzzer: QCMS color space and color transform
Add fuzzer that reads test input and creates a color profile
from it (or bails if not). Given that profile |test|, create
another profile |srgb| used to transform colors to/from when
running the color transform fuzzer test stage.
Test ICC version 2 profiles only since ICC version 4 support
in QCMS is not enabled in Chrome.
Add third_party/qcms/DEPS: allows qcms_color_space_fuzzer to
use //base and //testing code.
Speed: achieves ~2300 execs/s on Mac Air. Seed corpus of ICC
profiles uploaded to qcms_color_space_fuzzer GCS bucket.
Set max_len to 4Meg (color profiles can be large and this is
the limit that Chrome accepts), and use the ICC profile dict
