bp #57519
Problem Summary:
This PR adds a TotalGetRequestTime profile metric to the S3 reader. The new metric records the total time spent on all GetObject requests, which will be useful for future performance analysis and optimization.

Example profile (Some less relevant information was manually removed.):

FILE_SCAN_OPERATOR  (id=0.  nereids_id=104.  table  name  =  lineitem):
      CommonCounters:
            -  ExecTime:  11sec669ms
            -  OpenTime:  7.395ms
            -  WaitForDependency[FILE_SCAN_OPERATOR_DEPENDENCY]Time:  11sec634ms
              ....
