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.

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.

app/vmalert/rule: reduce number of allocations for getStaleSeries fn (#6269 )

Allocations are reduced by re-using the byte buffer when converting
labels to string keys.
```
name               old allocs/op  new allocs/op  delta
GetStaleSeries-10       703 ± 0%       203 ± 0%   ~     (p=1.000 n=1+1)
```
