### What changes were proposed in this pull request?
Disallow comparison between Interval and String in the default type coercion rules.
### Why are the changes needed?
If a binary comparison contains interval type and string type, we can't decide which
interval type the string should be promoted as. There are many possible interval
types, such as year interval, month interval, day interval, hour interval, etc.
### Does this PR introduce _any_ user-facing change?
No, the new interval type is not released yet.
### How was this patch tested?
Existing UT
Closes#33750 from gengliangwang/disallowCom.
