Storages: Update the length of Block queue and the number of read threads (#8702)

[ti-chi-bot]

This is an automated cherry-pick of #8702

What problem does this PR solve?

Issue Number: close #8703

What is changed and how it works?

• The length of Block queue:

  • For on-premise deployment, adjusting the length of the Block queue to 1.5 times of the current default value is expected to reduce the time required for simple queries by 3-6%.
  • For disaggregated deployment, adjusting the length of the Block queue to 1.5 times of the current default value is expected to reduce the time required for simple queries by 2-20%. The specific performance improvement depends on data caching. The less cached data, the more significant the improvement.

• The number of read threads:

  • For disaggregated deployment, if most of the data cannot hit the local disk cache, the network will become a bottleneck, and increasing the number of threads can significantly improve performance. If more than half of the data is expected to hit the local cache, adjusting the number of threads to 2 times of the current default value is enough.
