Stash `left_joins` into `joins` to deduplicate redundant LEFT JOIN
Originally the `JoinDependency` has the deduplication for eager loading
(LEFT JOIN). This re-uses that deduplication for `left_joins`.
And also, This makes left join order into part of joins, i.e.:
Before:
```
association joins -> stash joins (eager loading, etc) -> string joins -> left joins
```
After:
```
association joins -> stash joins (eager loading, left joins, etc) -> string joins
```
Now string joins are able to refer left joins.
Fixes #34325.
