lib/bytesutil: split Resize() into ResizeNoCopy() and ResizeWithCopy() functions
Previously bytesutil.Resize() was copying the original byte slice contents to a newly allocated slice.
This wasted CPU cycles and memory bandwidth in some places, where the original slice contents wasn't needed
after slize resizing. Switch such places to bytesutil.ResizeNoCopy().

Rename the original bytesutil.Resize() function to bytesutil.ResizeWithCopy() for the sake of improved readability.

Additionally, allocate new slice with `make()` instead of `append()`. This guarantees that the capacity of the allocated slice
exactly matches the requested size. The `append()` could return a slice with bigger capacity as an optimization for further `append()` calls.
This could result in excess memory usage when the returned byte slice was cached (for instance, in lib/blockcache).

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]`
