IMPALA-9829: Add Write Metrics for Spilling

Three types of metrics are added in disk-io-mgr:
1. impala-server.io-mgr.queue-$0.write-latency, unit: ns,
kind: HistogramMetric
2. impala-server.io-mgr.queue-$0.write-size, unit: Bytes,
kind: HistogramMetric
3. impala-server.io-mgr.queue-$0.write-io-error, kind:IntCounter

Write size, latency and io errors will be recorded in
impala::io::DiskIoMgr::Write.

Testing:
 * added DiskIoMgrTest.MetricsOfWriteSizeAndLatency
 * added DiskIoMgrTest.MetricsOfWriteIoError
Ran unit test disk-io-mgr-test and pre-commit test
