bitbake: bitbake: cooker: Split file collections per multiconfig

Splits the cooker to track a collection per multiconfig instead of a
single collection for all multiconfigs. Practically speaking, this
allows each multiconfigs to each have different BBMASKs that apply to it
instead of each one using the mask specified in the base configuration.
