John Stiles dbd4e6f0c0 Move ProgramKind and ProgramSettings types out of SkSL::Program.
This change will allow these types to be forward-declared; C++ doesn't
allow forward declaration of types declared inside a struct. Moving
these types out of Programs resulted in a large diff.

The Settings::Value helper class has been moved inside of the
IRGenerator. In practice, it was actually just an implementation detail
of how IRGenerator looks up caps-values by name. It seems very unlikely
that this will be necessary elsewhere going forward.
