  1. [BugFix] Support Generated Column rewrite for logical view with custo… 

    …mize column name

Why I'm doing:
In current implementation, if the logical view sepcify the customize column name which is different
from the projection output of the SQL definition, optimizer will not rewrite Generated Column expression
although all column have been outputed.
This issue is caused by lack of alias information in SelectItem in this case. The alias information can be
found in scope for logical view.

What I'm doing:
1. Use alias information in scope for logical view rewriting.
2. Refactoring some code.
