issue: #34595
When consuming insert data on the delegator node, QueryCoord will move
out some sealed segments to manage its memory usage. After the growing
segment gets flushed, some sealed segments from other workers will be
moved back to the delegator node. To avoid the frequent movement of
segments, we estimate the maximum growing row count and preserve a
fixed-size memory in the delegator node.

Benchmark case: The benchmark run the go benchmark function
`BenchmarkDeltalogFormat` which is put in the Files changed. It tests
the performance of serializing and deserializing from two different data
formats under a 10 million delete log dataset.
Metrics: The benchmarks measure the average time taken per operation
(ns/op), memory allocated per operation (MB/op), and the number of
memory allocations per operation (allocs/op).
| Test Name | Avg Time (ns/op) | Time Comparison | Memory Allocation
(MB/op) | Memory Comparison | Allocation Count (allocs/op) | Allocation
