Signed-off-by: wjhuang2016 huangwenjun1997@gmail.com

What problem does this PR solve?

Issue Number: close #31216

Problem Summary:
When building range for scalarfunction, we should not use expr.CharsetAndCollation() to get the collation.
For col1 > 'a' or col1 >'b' , it always gets binCollation.
So we need to pass collation to Build().

What is changed and how it works?

Pass column's collation to Build() and use it.
