Rename o.e.common in libs/core to o.e.core (#73909)

When libs/core was created, several classes were moved from server's
o.e.common package, but they were not moved to a new package. Split
packages need to go away long term, so that Elasticsearch can even think
about modularization. This commit moves all the classes under o.e.common
in core to o.e.core.
