types: improve the typing of FilterQuery<T> type to prevent it from only getting typed to any

Re: #14398
Fix #14397

@FaizBShah WDYT?

Summary

#14398 but with a couple of changes:

1. Avoided changing FilterQuery<RawDocType> back to FilterQuery<DocType> for everything but getFilter() and getQuery(). For some reason, tests fail without that
2. Fixes for the [Types] Adjusments to ApplyBasicQueryCasting (ff2bf3e8b3abe0e09a523465e5db8743083702b9) break FilterQueries for generic types #11964 test. The fact that we had to change that test was concerning, but after diving down the rabbit hole I'm convinced the [Types] Adjusments to ApplyBasicQueryCasting (ff2bf3e8b3abe0e09a523465e5db8743083702b9) break FilterQueries for generic types #11964 test is just incorrect and will never work unless FilterQuery types to any. Here's a couple of TypeScript playground examples demonstrating the issue, which is that with class Repository<T>, there's no way to type T so that T excludes { id: never }, and WithId<{ id: never }> still types to {id: never}.

Examples

Yeah, this looks good to me!! Even I personally didn't liked changing RawDocType to to DocType everywhere, but did it because I thought maybe some types might fail, but this soln. looks cleaner. And yes, the test was incorrect because it was written with the assumption that id will never be able to be never. LGTM!!

Looks good to me, though i am not really involved with the semantics of these types.

maybe we can make / have a helper that is a BasicPojoDocument for easy / quick / shared access
