[yocto-autobuilder-helper][PATCH v2 04/10] scripts/utils: add getconfigdict() for dict-type config values

From: Tim Orling <[email protected]>

Parallel to getconfiglist(), but for JSON object values. The merge
priority is defaults < target-level < step-level so that more-specific
keys win: a step can override individual entries in a target-level dict
without replacing the whole thing, and both levels refine the defaults.

Used by the upcoming CONTAINER_IMAGES support, where each entry maps a
Yocto recipe name (the on-disk OCI path stem) to an image name (the
name pushed to the container registry).
