Ethan Nicholas c845272b4e Broke DSLWriter into two separate classes
As DSLWriter evolved, it ended up performing two unrelated duties:

1. Holding per-thread state which is referenced throughout SkSL
   (including non-DSL code)
2. DSL-specific utility functions

There's no reason for those to be contained in the same class, and
there's also no reason the per-thread state should be held in a
DSL-specific class. This breaks out an SkSL::ThreadContext class to hold
the state info, leaving the DSL utility functions behind in DSLWriter
(which should perhaps be renamed, but that's a job for a future CL).
