Adapter side of elixir-ecto/ecto#4765 (fix for elixir-ecto/ecto#4763), which is now merged. Supersedes #747, whose changes are folded into this PR.

Ecto's join builder now emits every JoinExpr.on as a %BooleanExpr{op: :and} instead of a QueryExpr, so that wheres folded into the on of an interpolated join query (join: x in ^query) can carry subqueries. This matches on BooleanExpr when rendering joins, and drops the manual struct rewrite in the using_join comprehensions (Map.put(:__struct__, BooleanExpr) |> Map.put(:op, :and)), which now receive a real BooleanExpr.

Two failure modes without this change:

• join/2 raises FunctionClauseError for any interpolated join query — loud.
• the using_join comprehensions filtered joins by on: %QueryExpr{}, so they would silently drop the join conditions from the WHERE clause of update_all/delete_all — wrong SQL, no error. There was no coverage for interpolated join queries in update_all/delete_all, so this adds it for all three adapters.

mix deps.update ecto bumps the ecto git dep to 8959c439, which includes the change. Full suite passes (692 tests), along with mix format --check-formatted and mix deps.unlock --check-unused.
