Ensure the CommandSwitches::Get() singleton is properly initialized.

Otherwise, flags like `--as=buildfile` are ignored. This caused a
GN autoroll failure in Chromium. This fixes the issue by ensuring
that CommandSwitches::Init() is called from main(), and by adding
runtime checks to verify CommandSwitches::Get() and
CommandSwitches::Set() are always called after
CommandSwitches::Init().
