Reload: deprecate consecutive reload duration time metrics

Deprecate metrics that were introduced to monitor reload duration times
to investigate a chance to detect a signal for users' reload intention.
But, we could not figure out good characteristics to utilize this

This change effectively reverts the following CL, but the reload_type_
in NavigationHandleImpl will be remained because it's now used for
another purpose.
