DATACMNS-1357 - Use shared DefaultConversionService in ProxyProjectionFactory and ResultProcessor.

Browse Source 
ProxyProjectionFactory and ResultProcessor require a DefaultConversionService to convert values for projection proxies and to post-process query method results. Creating instances of these types requires an instance of the conversion service which previously created a DefaultConversionService instance (along all converter registrations) upon ProxyProjection/ResultProcessor instantiation.

We now use the shared instance that is initialized once and shared across all ProxyProjection/ResultProcessor instances to reduce garbage and improve the CPU profile.
