CTE (Common Table Expression) with aliases support

[typeless]

After https://gitea.com/xorm/builder/pulls/59 we can do
Join(Select(...), ...)
It would be more useful if it can support aliases like the following SQLs (SQLite dialect):

WITH r AS (
  SELECT * 
  FROM 
  repository
), u AS (
  SELECT * 
  FROM 
  user
) SELECT 
  u.name, 
  r.name 
FROM 
  u 
JOIN 
  r ON u.id = r.owner_id;

SELECT 
  user.id, 
  r.name 
FROM 
  user 
JOIN (
  SELECT * 
  FROM 
  repository) AS r ON user.id = r.owner_id;

Note that builder.From supports aliases already. This issue is mainly about builder.Join.
