[material-ui] Deprecate composed CSS classes #41282
Description
Part of #40417
Description
Deprecate composed CSS classes, which are planned for removal in v7.
- These are deprecated in favor of using atomic classes and combining them in userland
- If the atomic classes do not exist, they must be implemented in the same PR in which the deprecation is added
- The PR introducing the deprecation must also add:
- A section in the migration guide
- A codemod
