fix(chore): remove static type references for slotClassNames

[kuzhelov]

TODO

• introduce changelog entry

---

This PR temporarily removes static type references from slotClassNames, as it serves as a source of circular dependencies problem. This move doesn't introduce breaking changes to the client and, at the same time, provides us with some time to

• introduce necessary checks to detect malicious circular dependencies
• come up with better approach to handle potential duplications in slotClassNames strings (although, most of them have reasons to exist).

This fix also removes circular dependency between Menu -> MenuItem -> Menu that currently fails docs from start.
