Enhance logging for timed out transport requests (#64433)

Apropos of nothing—

The current logging:

Received response for a request that has timed out, sent [2148898ms] ago, timed out [348859ms] ago

This just saves having to do the mental math for milliseconds and produces:

Received response for a request that has timed out, sent [35.8m/2148898ms] ago, timed out [5.8m/348859ms] ago
