Ryuta Kamizono b4478ae8bc Preserve user supplied joins order as much as possible 
Currently, string joins are always applied as last joins part, and Arel
join nodes are always applied as leading joins part (since #36304), it
makes people struggled to preserve user supplied joins order.

To mitigate this problem, preserve the order of string joins and Arel
join nodes either before or after of association joins.

Fixes #36761.
Fixes #34328.
Fixes #24281.
Fixes #12953.
