[compiler] Don't validate when effect cleanup function depends on effect localized setState state derived values (#35020)

Summary:
If we are using a clean up function in an effect and that clean up
function depends on a value that is used to set the state we are
validating for we shouldn't throw an error since it is a valid use case
for an effect.

Test Plan:
added test
