I am debugging OOM issues with DataFusion Comet and find it useful to know
which consumer/reservation is failing to grow its reservation.
Before:
```
Additional allocation failed with top memory consumers (across reservations)
as:
ExternalSorter[53]#1569(can spill: true) consumed 262.8 MB, peak 271.9 MB,
ExternalSorterMerge[53]#1570(can spill: false) consumed 5.5 MB, peak 10.0
MB,
ExternalSorterMerge[53]#1568(can spill: false) consumed 5.0 MB, peak 10.0
MB,
SMJStream[53]#1571(can spill: false) consumed 0.0 B, peak 0.0 B,
GroupedHashAggregateStream[53] ()#1572(can spill: true) consumed 0.0 B,
peak 0.0 B,
GroupedHashAggregateStream[53] ()#1573(can spill: true) consumed 0.0 B,
peak 0.0 B.
```
After:
```
try_grow failed for ExternalSorterMerge[53]: Additional allocation failed
with top memory consumers (across reservations) as:
ExternalSorter[53]#1569(can spill: true) consumed 262.8 MB, peak 271.9 MB,
ExternalSorterMerge[53]#1570(can spill: false) consumed 5.5 MB, peak 10.0
MB,
ExternalSorterMerge[53]#1568(can spill: false) consumed 5.0 MB, peak 10.0
MB,
SMJStream[53]#1571(can spill: false) consumed 0.0 B, peak 0.0 B,
GroupedHashAggregateStream[53] ()#1572(can spill: true) consumed 0.0 B,
peak 0.0 B,
GroupedHashAggregateStream[53] ()#1573(can spill: true) consumed 0.0 B,
peak 0.0 B.
```

they covered by existing tests)?
