gfx: Make display lists serializable using serde
.
This commit introduces the `serde` dependency, which we will use to serialize messages going between processes in multiprocess Servo. This also adds a new debugging flag, `-Z print-display-list-json`, allowing the output of display list serialization to be visualized. This will be useful for our experiments with alternate rasterizers.
