tsdb: check for context cancel before regex matching postings (#14096)
* tsdb: check for context cancel before regex matching postings

Regex matching can be heavy if the regex takes a lot of cycles to
evaluate and we can get stuck evaluating postings for a long time
without this fix. The constant checkContextEveryNIterations=100
may be changed later.

Bryan Boreham 10eb23bd6b [TEST] Rules: Sleep 15ms to fit Windows behaviour better
On Windows, Go will sleep 15ms if you ask for less.  TestAsyncRuleEvaluation
compares actual delay to the nominal time, so using 15ms should work
better on Windows, and be hardly noticeable elsewhere.

[ENHANCEMENT] TSDB: Optimize querying with regexp matchers
Add method `PostingsForLabelMatching` to `tsdb.IndexReader`, to obtain postings for labels with a certain name and values accepted by a provided callback, and use it from `tsdb.PostingsForMatchers`.
The intention is to optimize regexp matcher paths, especially not having to load all label values before matching on them.

Plus tests, and refactor some `tsdb/index.Reader` methods.

Benchmarking shows memory reduction up to ~100%, and speedup of up to ~50%.

Quote label name in matchers when needed
When the label name of a matcher contains non-standard characters, like
a dot, or starts with a digit, it should be quoted.

If it's not quoted, then `VectorSelector.String()` isn't a valid PromQL.

[REFACTOR] PromQL: simplify rangeEvalTimestampFunctionOverVectorSelector (#14021)
The function `rangeEvalTimestampFunctionOverVectorSelector` appeared to be checking histogram size, however the value it used was always 0 due to subtle variable shadowing.
However we don't need to pass sample values to the `timestamp` function, since the latter only cares about timestamps. This also affects peak sample count in statistics, since we are no longer copying histogram samples.

Fix parser.VectorSelector.String() with empty name matcher (#14015)
The check fell into "this matcher equals vector selector's name" case when vector selector doesn't have a name and the matcher is an explicit matcher for an empty __name__ label.

To provide some context about why this is important: some downstream projects use the promql.Parse(expr.String()) to clone an expression's AST, and with this bug that matcher disappears in the cloning.
