simput support updates
A number of improvements that improve simput support. Commiting to avoid having a large diff later.
Adds support for:
- vtkSMProxyListDomain, vtkSMStringListDomain
- AdvancedDecorator
- 'qProxySelectionWidget' maps to "sw-select"
- better validation of input type for SetProperties in microservices. Helps when we pass simput proxy instead of paraview proxy.
- Exposes more properties for the GeometryRepresentation proxy.
