Motivation

In the sculpting workflow it is a common step to always apply the scaling of an object so that the tools, brushes and operations work as expected.
This is adding extra steps for the user for something that could be automated or fixed. It also confuses most beginners who need to learn this the hard way.

Proposal

Add a prompt when entering sculpt mode on an object that has non-unform scaling. This popup will behave similarly to enabling dyntopo while having object data that could be destroyed by using that option:

This popup will ask the user " Warning!"
"You are entering sculpt mode on an object with non-uniform scaling values. We recommend to apply the scaling of the object before proceeding."

It will then offer 2 options: "Apply Scale" which is highlighted and will be used when pressing enter, and "Don't Apply" which enters sculpt mode regardless without applying the scale.

If the scaling is applied the normals should also be recalculated if the scale was negative. This will save the user some trouble of going into edit mode and doing this manually.

Issues

Certain bugs would lead to progress being destroyed such as #74361.
These need to be resolved first.

Also ff the user wants to keep the scale intact it will also prompt them every time they enter sculpt mode. Potentially this is not ideal but still better than not having the prompt.
