Parse: tree update for visitor

[Yaiba]

This pr is for the changes need to be made for query cost estimate.

• 4b4dba2 support visitor on AstNode, along with exisiting listener(still working)
• 8dddb75 new tree.Relation to replace TableOrSubquery+JoinClause, this require
• • relation and statement node update sql-grammar#4
• • sqlparser call signature adjustment kuneiform#54
• 4a0e216 unify statement structure shape
• • remove FromClause
• b8c4e45 move sql-grammar-go to kwil-db
• • new task antlr:sql to generate antlr code

@brennanjl I kind combined multiple changes on tree node in this pr.
For Visitor, I haven't really used it ever since I change my implementation on query plan, but a lot of repeated changes are included, extra effort might be needed to make it actually work

[Yaiba]

To merge this, do those steps:

• merge relation and statement node update sql-grammar#4

Then

• update go.mod in sqlparser call signature adjustment kuneiform#54, then merge
• create a new pr to use new kuneiform version
