  [NFC][Coro] Remove now unused CommonDebugInfo in CoroSplit (#129150)


Summary:
This cleans up the now unnecessary debug info collection in CoroSplit.

This makes CoroSplit pass almost as fast with -g2 as it is with -g1 on
the sample cpp file used with other parts of this stack:

|                 | Baseline | IdentityMD set | Prebuilt CommonDI | MetadataPred (cur) |
|-----------------|----------|----------------|-------------------|--------------------|
| CoroSplitPass   | 306ms    | 221ms          | 68ms              | 3.8ms              |
| CoroCloner      | 101ms    | 72ms           | 0.5ms             | 0.5ms              |
| CollectCommonDI | -        | -              | 63ms              | -                  |
| Speed up        | 1x       | 1.4x           | 4.5x              | 80x                |
