Move |kSwitchNames| to anonymous namespace.

This makes GpuProcessHost::LaunchGpuProcess significantly easier to read.
This is in preparation for getting rid of the GPU broker process.
Also make "GPU process" capitalization consistent.

BUG=329375
TEST=content_shell boots, --disable-gpu-sandbox gets propagated.
