Instead of looking up casts at parse time for converting the result of JsonPath* query functions to the specified or the default RETURNING type, always perform the conversion at runtime using either the target type's input function or the function json_populate_type(). There are two motivations for this change: 1. json_populate_type() coerces to types with typmod such that any string values that exceed length limit cause an error instead of silent truncation, which is necessary to be standard-conforming. 2. It was possible to end up with a cast expression that doesn't support soft handling of errors causing bugs in the of handling ON ERROR clause. JsonExpr.coercion_expr which would store the cast expression is no longer necessary, so remove. Bump catversion because stored rules change because of the above removal.
