[Visualizations] Adds visConfig.title and uiState to build pipeline f…

…unction (#2192) (#2272)

In pipeline building, this PR adds `visConfig.title` and `uiState` properties for "visualization" function.

This aims 2 goals:
-    To be consistent with pipelines built with "buildPipelineVisFunction".
-    To provide "title" and "uiState" informations for visualizations.

This is currently a missing information for community plugins.
