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.

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.
