Quickstep-63 Fix PlanVisualizer's crashes on physical plans unsupported by
StarSchemaSimpleCostModel.
`PlanVisualizer` would result in crashes on some queries (i.e.,
`CreateTable`) which do not have corresponding physical plan support in
`StarSchemaSimpleCostModel::estimateCardinality`.
This PR fixes this problem by:
(1) Let the cost models throw `UnsupportedPhysicalPlan` exception for
unsupported plans.
(2) `PlanVisualizer` simply catches the exceptions and omits the
cardinality info for unsupported physical nodes.
