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).

issue: #34095
When a new query node comes online, the segment_checker,
channel_checker, and balance_checker simultaneously attempt to allocate
segments to it. If this occurs during the execution of a load task and
the distribution of the new query node hasn't been updated, the query
coordinator may mistakenly view the new query node as empty. As a
result, it assigns segments or channels to it, potentially overloading
the new query node with more segments or channels than expected.
This PR measures the workload of the executing tasks on the target query
node to prevent assigning an excessive number of segments to it.
