SkColorSpaceXform: clamp before table lookups
The fuzzer has built a single test case that causes out-of-bounds reads on both the src and dst tables. I'm glad we have it. Next follow ups may include: - have byte_tables_rgb do its own clamping - replace table_{r,g,b} here with a single stage analogous to byte_tables_rgb that looks up the three float tables safely - maybe replace byte_tables_rgb with that. I'm not really sure why src->XYZ tables are floats but XYZ->dst are bytes. I'm going to try some of these out before attempting to reland in Chrome. As usual, rebaselining Blink makes things a pain.
