more schema tweaks for parameter objects (OAI#2811)

* allowEmptyValue is valid only for query parameters

https://spec.openapis.org/oas/v3.1.0#parameter-object

we can't move this to the dependentSchemas section because that is only valid
when "schema" is present.

* allowReserved only applies to parameters with a value of query
