Since spring-projects/spring-framework#23314 and the following commit
spring-projects/spring-framework@be4facef1b, the RSocket codec selection
is relaxed and the order of configured commits matters again.

This commit ensures that the CBOR codec is configured ahead of the JSON
codec so that it can be chosen first if no data mime type is specified
when a connection is established with a client requester.

Since spring-projects/spring-framework#23314, the `RSocketStrategies`
provide more codecs by default, and there is no need to order them to
avoid conflicts during mime type selection.

This commit also ensures that the `PayloadDecoder.ZERO_COPY` is
configured on the RSocket server if the configured `DataBufferFactory`
is compatible with that strategy.

Extend `JsonContentAssert` with `hasJsonPath` and `doesNotHaveJsonPath`
methods which can be used to check the path regardless of the value it
may or may not contain.

Prior to this commit there wasn't an easy way to assert that the
Jackson `@JsonInclude(JsonInclude.Include.NON_NULL)` annotation was
applied since `assertDoesNotHavePathValue` would pass for both
`{"name" : null}` and `{}`.
