Description

With Psycopg3 offering async connections and async cursors, we can start implementing at least part of DEP0009 on the ORM

The first step would be just a low-level API, so that we can make the async cursor available to our users:

from django.db import new_connection

async with new_connection(using="default") as conn:
    async with conn.acursor() as c:
        await c.execute(...)

Note: In order to have a simpler and easier review, I've considered transaction.atomic out of scope for this ticket.

I see this was suggested as part 1 of a plan here: ​https://forum.djangoproject.com/t/dep0009-orm-implementation-plan/33194 with some positive feedback from Andrew Godwin
Tentatively accepted
