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.

Oleg Zaytsev 4b7a44c7a0
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.

parser: remake generated_parser output (#13923) 
In a previous PR, the generated parser was created using an old version of goyacc.

Also adds -l to disable line directives, which fixes debug processing and reduces diffs at the expense of making it more difficult to reason about the generated output.
