[FEATURE] PromQL: Add experimental info function MVP (#14495)
The `info` function is an experiment to improve UX
around including labels from info metrics.
`info` has to be enabled via the feature flag `--enable-feature=promql-experimental-functions`.

This MVP of info simplifies the implementation by assuming:
* Only support for the target_info metric
* That target_info's identifying labels are job and instance

Also:
* Encode info samples' original timestamp as sample value
* Deduce info series select hints from top-most VectorSelector
