[Generator] Add support of deepObject style in query params

### Motivation apple#259 ~Depends on apple/swift-openapi-runtime#100 landing first and getting released, and the version dependency being bumped here.~ ### Modifications Added `deepObject` style to serializer & parser in order to support nested keys on query parameters. ### Result Support nested keys on query parameters. ### Test Plan Adapted snippet tests (SnippetBasedReferenceTests)
