Title: Add isLoaded to DS.ManyArray and to DS.RecordArray

We always give adapter "record array" so it can mark it as loaded or in the future we could mark it as error
For single resources loading, we use didFindRecord

This is a WIP, this main issue is the default `findMany` implementation that calls `find` for every record, so we loose the possibility to call `load` on given `manyArray`
