[Merged by Bors] - perf(CategoryTheory/Limits/Shapes): reorder instance arguments

[JovanGerb]

This PR is in the same spirit as #22953.

The problem is that some instances about category theoretical limits have silly side conditions that end up searching through the whole algebraic type class hierarchy. This PR attempts to keep the type class search limited to category theoretical type classes.

• 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).
