vendor: update github.com/VictoriaMetrics/metricsql from v0.37.0 to v0.38.0
This adds more optimization cases for https://utcc.utoronto.ca/~cks/space/blog/sysadmin/PrometheusLabelNonOptimization

For example:

* Multi-level transform functions. For example, abs(round(foo{a="b"})) + bar{x="y"}
  is now optimized to abs(round(foo{a="b",x="y"})) + bar{a="b",x="y"}
* Binary operations with `on()`, `without()`, `group_left()` and `group_right()` modifiers.
  For example, foo{a="b"} on (a) + bar is now optimized to foo{a="b"} on (a) + bar{a="b"}
* Multi-level binary operations. For example, foo{a="b"} + bar{x="y"} + baz{z="q"}
  is now optimized to foo{a="b",x="y",z="q"} + bar{a="b",x="y",z="q"} + baz{a="b",x="y",z="q"}
* Aggregate functions. For example, sum(foo{a="b"}) by (c) + bar{c="d"}
  is now optimized to sum(foo{a="b",c="d"}) by (c) + bar{c="d"}

lib/{mergeset,storage}: properly limit cache sizes for indexdb
Previously these caches could exceed limits set via `-memory.allowedPercent` and/or `-memory.allowedBytes`,
since limits were set independently per each data part. If the number of data parts was big, then limits could be exceeded,
which could result to out of memory errors.

* 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]`

docs/Single-server-VictoriaMetrics.md: document that the deduplication is applied only when exporting data in JSON line format
The exported data isn't de-duplicated by default due to performance reasons.
It is expected that the de-duplication is applied during importing the exported data.

The deduplication is applied only when exporting data via /api/v1/export if `reduce_mem_usage=1` query arg isn't passed to the request.
