Add push button support for OFX plugins

Browse Source 
This commit adds support for push buttons in OFX plugins by:

- Adding `kPushButton` to `NodeValue` enum
- Implementing `pushButtonClicked` slot in `PluginNode`
- Creating `NodeParamButton` widget for UI representation
- Updating `paraminstance.h` to handle push button instances
- Modifying `nodeparamviewwidgetbridge.cpp` to connect push button signals
