SERVER-39085 fix index build setup in the IndexBuildsCoordinator during secondary oplog application

New index builds are ignored if the same indexes are already being built.
IndexBuildsCoordinator does not add collation defaults or filter indexes on secondaries.
MultiIndexBlock adds index build info to CurOp for identification purposes.
