Don't use GLStateRestorer with the passthrough command decoder.

The passthrough command decoder does not implement the state restoration
functions because it does not track state. When a GLStateRestorer
exists, it is used for the scoped binders in ui/gl/scoped_binders.h and
leads to incorrect state being applied.
