Brian Osman c7ad40f76f Remove SK_SUPPORT_GPU checks in tool-only code 
Most of this is (obviously) not necessary to do, but once
I started, I figured I'd just get it all. Tools (nanobench,
DM, skiaserve), all GMs, benches, and unit tests, plus support
code (command line parsing and config stuff).

This is almost entirely mechanical.
