bitbake: cache: Build datastores from databuilder object

Rather than passing in a datastore to build on top of, use the data builder
object in the cache and base the parsed recipe from this. This turns
things into proper objects building from one another rather than messy
mixes of static and class functions.

This sets things up so we can support parsing and building multiple
configurations.
