changes: * add `ApplyFunction` support to vectorization fallback, allowing many of the remaining expressions to be vectorized * add `CastToObjectVectorProcessor` so that vector engine can correctly cast any type * add support for array and complex vector constants * reduce number of cases which can block vectorization in expression planner to be unknown inputs (such as unknown multi-valuedness) * fix array constructor expression, apply map expression to make actual evaluated type match the output type inference * fix bug in array_contains where something like array_contains([null], 'hello') would return true if the array was a numeric array since the non-null string value would cast to a null numeric * fix isNull/isNotNull to correctly handle any type of input argument
