Interpreter: Vectorized interpreter

This converts the SkSL interpreter to operate in SIMT fashion. It handles
all the same features as the previous scalar implementation, but operates
on N lanes at a time. (Currently 8).

It's modeled after GPU and other parallel architectures, using execution
masks to handle control flow, including divergent control-flow.
