app/vmselect/promql: properly keep metric names when optimized path is used for aggregate function calculations
...
For example, `sum(rate(...) keep_metric_names) by (__name__)` didn't leave the original metric name because of this issue.

app/vmselect/promql: add support for @
modifier
...
Add support for `@` modifier in MetricsQL according to https://prometheus.io/docs/prometheus/latest/querying/basics/#modifier
Extend the support with the following features:
* Allow using `@` modifier everywhere in the query. For example, `sum(foo) @ end()`
* Allow using arbitrary expression as `@` modifier. For example, `foo @ (end() - 1h)`
returns `foo` value at `end - 1 hour` timestamp on the selected time range `[start ... end]`
