[Port to 2.x]: feat: report user query bytes (#27188)

Port master-1.x commit https://github.com/influxdata/influxdb/commit/858a2c6952 to main-2.x.

1.x records per-user query response bytes via the monitor statistics. 2.x has no equivalent; needs re-implementation on the http/metric event recorder / prometheus metrics, gated by a flag because of per-user label cardinality.
