Refactor SkVMGenerator construction.
Previously, the ctor for SkVMGenerator did a lot of setup work and
emitted the global-variable logic directly. Callers were responsible for
calling `writeFunction` exactly one time, to emit main.
Now, the ctor of SkVMGenerator just sets up members, and callers need to
call `writeProgram`. `writeProgram` emits all the setup code as well as
main.
This makes the ctor a little less scary looking, and gives us a natural
place to insert a dsl::Start/End pair.
