Fix dawn tests not using CLI adapter toggles

For example, `--disable-toggles=use_dxc` was being ignored. Use the
ParamTogglesHelper to collect all adapter toggles, as we do for device
toggles.

Note that we were previously needlessly passing in force
enabled/disabled *device* toggles in the adapter options. This no longer
happens now as ParamTogglesHelper filters the toggles by stage.
