MB-37096: Debug CRT: Reduce ep_perfsuite workload size further

ep_perfsuite tests still runn quite slowly under Windows Debug
CRT, of the order of 600s on CV machines.

Given we only run this in Debug mode for functional testing, reduce the
ize of the workload (vbucket couns, iterations of stats tests) so it
runs in a more reasonable duration.

This change reduces the runtime of ep_perfsuite.value_eviction from 200s
to 20s.
