Bogdan Chadkin 73767437b6 feat: forbid data variables with the same name on instance (#4771)
Ref https://github.com/webstudio-is/webstudio/issues/4768

We don't want to allow data variables on one instance with the same
name. Though we will allow child variables to mask parent ones in
another PR.


To test:
- create variable var1 on box
- try to create another variable with var1
- create variable var2
- try to rename it to var1
- create variable on body with var1
