app/vmalert: improve performances when rules produce large volumes of results
...
1. Avoid storing the last evaluation results outside of rules, check for
stale time series as soon as possible;
2. remove duplicated template `Clone()`.
This pull request is primarily reducing memory usage when rules produce
large volumes of results, as seen in
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6894 .
The CPU time spent on garbage collection remains high and may be
addressed in a separate PR.

lib/promutils, app/vmalert-tool/unittest: move promutils.Duration.ParseTime() to app/vmalert-tool/unittest.durationToTime()
...
The ParseTime() function looks strange, since it converts relative duration to absolute time since Unix Epoch.
In most scenarios such a conversion is used by mistake.
It is better to do not expose such a function for public use and hide it inside the package where it is needed,
e.g. inside app/vmalert-tool/unittest.
