[Vis builder] Persist data when switching visualization types

[ashwin-pc]

Currently the field values are cleared when the user switches between vis types. VisBuilder should be able to persist values across compatible types and ideally between incompatible types too to whatever degree possible.

Tasks:

• Investigate potential persistence solutions
• Investigate how the solutions will scale with varying visualization types (May tie into Visualization Abstractions)
• Implement persistence
• Functional tests

Split into sub tasks.

The first two subtasks are finished in these two issues: #2900 and #3482

Close this issue as the aggregation persistence has been implemented in this PR: #3495
