Support using function on join conditions

Support query such as match (a), match (b) where trim(a.xx)=b.xx+"__" return a

Hi @ted-wq-x, this isn't something that we would prioritize in the short term, but @andyfengHKU can maybe get back to you with a workaround (if you could elaborate a bit more on what exactly is the blocker here).

I'll need at least two weeks before I can get on this.

I think this is more of a performance issue rather than a correctness issue.
