SIM300: CONSTANT_CASE variables are improperly flagged for yoda violation (#9164)
## Summary

fixes #6956 
details in issue

Following an advice in
https://github.com/astral-sh/ruff/issues/6956#issuecomment-1817672585,
this change separates expressions to 3 levels of "constant likelihood":
*  literals, empty dict and tuples... (definitely constant, level 2)
*  CONSTANT_CASE vars (probably constant, 1)
* all other expressions (0)

a comparison is marked yoda if the level is strictly higher on its left
hand side

following
https://github.com/astral-sh/ruff/issues/6956#issuecomment-1697107822
marking compound expressions of literals (e.g. `60 * 60` ) as constants
this change current behaviour on
`SomeClass().settings.SOME_CONSTANT_VALUE > (60 * 60)` in the fixture
from error to ok
