codeintel: Update lsif_index records to hold their own configuration
Created by: efritz
This adds a one-job structure based on the types added in https://github.com/sourcegraph/sourcegraph/pull/14356 into the lsif_index table.
This closes https://github.com/sourcegraph/sourcegraph/issues/13895 and enables https://github.com/sourcegraph/sourcegraph/issues/13896.
