[Merged by Bors] - chore(positivity): make tactic lemmas public

[JovanGerb]

This PR removes privateInPublic and private from all lemmas used by the positivity tactic. These lemmas are part of the public API of the positivity tactic, so it makes sense for the lemmas to be public. They all live in the Mathlib.Meta.Positivity namespace, so they can't be confused with user-facing lemmas.

• The relative value is the weighted sum of the differences with weight given by the inverse of the current value of the statistic.
• The absolute value is the relative value divided by the total sum of the inverses of the current values (i.e. the weighted average of the differences).
