feat: add 2d ConfigPresetsTable

[tlambert03]

continuing with views onto the new model from #447, this adds a 2D Config Table widget.

It represents a single Configuration group with presets as Columns (or rows), and the union of all dev-prop pairs as rows.

It's best suited for groups that share the same combo of device properties across all presets... but works either way. A missing Dev-Prop in a given preset will show as an empty cell

Double clicking on the cell reveals a property-value-specific editor widget

closes #320
