[FLINK-4070] [tableApi] Support literals on left side of binary expre…
The Table API does not support literals on left side of expressions like
`+,_,*,/,%,>,< `. Because there is already such method in Int class, scala
compiler would not search for implicit conversion.
So I add a function `toExpr` to Expression, now we can use 12.toExpr % 'f0.
It is a useful feature in some cases.

> The Table API does not support binary expressions like {{12 < 'f0}} in Scala
