(core) Move most of the reference parsing code into common so that the server can use it

Browse Source 
Summary: Refactoring in preparation for parsing strings from the API. The plan is that the API code will only need to do a server-side version of the code in ViewFieldRec.valueParser (minus ReferenceUtils) which is quite minimal.

Test Plan: Nothing extra here, I don't think it's needed. This stuff will get tested more in a future diff which changes the API.
