Drop inline manifests from resolver cache.
Drop inline manifests from resolver cache.

For cached catalog entries whose content is ultimately installed from
a referenced bundle image, any additional inlined manifests are bloat
in the resolver cache and can be removed. Ultimately, no bundle
references should be held by resolver cache entries, but the CsvJson
and Object bundle fields can be zeroed out now for an immediate heap
size reduction.
