[Metrics][Discover] use lastReloadRequestTime from fetchParam (#244761)

part of [239158](#239158)
## Summary

This PR is a follow-up from the changes made for
[239158](#239158).
`lastReloadRequestTime` was receiving `Date.now()` and this was causing
the chart to reload whenever it returned to the viewport. `fetchParams`
provides a `lastReloadRequestTime` attribute, which is safer to use

### How to test
- Start a local Kibana instance and point it to an oblt cluster 
```yml
feature_flags.overrides:
  metricsExperienceEnabled: true
 ```
- Navigate to Discover and Switch to ESQL mode
- After the grid loads, scroll up or down. The charts should not try to load data.
