    Allocate separate DSM chunk for parallel Index[Only]Scan instrumentation
    
    Previously, parallel index and index-only scans packed the parallel scan
    descriptor and shared instrumentation (for EXPLAIN ANALYZE) into a
    single DSM allocation. Since scans may be instrumented without being
    parallel-aware, and vice versa, using separate DSM chunks -- each with
    its own TOC key -- is cleaner. A future commit will extend this pattern
    to other scan node types.
