[objc] Let the developer specify the timezone to be used for date serialisation (#6628)

* [objc] Update deployment target to 8.0

Updates the test project deployment target to 8.0, as that's the lowest
supported by the latest XCode.

* [objc] Update petstore tests based on current master

Makes sure the tests are based on the latest version of master.

* [objc] Allow specifying the serialization timezone

Now it's possible to specify the timezone used for serializing dates
