VST3: program change message does not notify host about parameter changes

[Spacechild1]

When I change the VST3 program parameter, e.g. in the generic UI of Reaper or with the [program( message in the [vstplugin~] Pd external, Dexed does not tell which parameters have changed. Other VST3 plugins would call the restartComponent method with the kParamValuesChanged flag, so that the host can update its own parameter representation.

Tested with Dexed 0.9.6 (VST3) on Windows 10.
