feat(NumberTheory/Height/Basic): add {mul|log}Height_comp_le, {mul|log}Height_fun_mul_eq

[MichaelStollBayreuth]

This adds

• two missing logHeight lemmas (their mulHeight versions are already there)
• {mul|log}Height_comp_le: the height of x ∘ f is bounded by the height of x
• {mul|log}Height_fun_mul_eq: the height of the "multiplication table" fun (i, j) ↦ x i * y j is the {product|sum} of the heights of x and of y
• {mul|log}Height_fun_prod_eq: the analogous result for products with arbitrarily many factors
• plus some API lemmas needed for these.

• 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).
