Support for database/sql in migrations + framework for multi-driver River

Here, add a new minimal driver called `riverdriver/riversql` that
supports Go's built-in `database/sql` package, but only for purposes of
migrations. The idea here is to fully complete #57 by providing a way of
making `rivermigrate` interoperable with Go migration frameworks that
support Go-based migrations like Goose, which provides hooks for
`*sql.Tx` [1] rather than pgx.

`riverdriver/riversql` is not a full driver and is only meant to be used
with `rivermigrate`. We document this clearly in a number of places.

To make a multi-driver world possible with River, we have to start the
work of building a platform that does more than `riverpgxv5`'s "cheat"
workaround. This works by having each driver implement specific database
operations like `MigrationGetAll`, which target their wrapped database
package of choice.

This is accomplished by having each driver bundle in its own sqlc that
targets its package. So `riverpgxv5` has an `sqlc.yaml` that targets
`pgx/v5`, while `riversql` has one that targets `database/sql`. There's
some `sqlc.yaml` duplication involved here, but luckily both drivers can
share a `river_migration.sql` file that contains all queries involved,
so you only need to change one place. `river_migration.sql` also migrates
entirely out of the main `./internal/dbsqlc`.

The idea here is that eventually `./internal/dbsqlc` will disappear
completely, usurped entirely by driver-specific versions. As this is
done, all references to `pgx` will disappear from the top-level package.
There are some complications here to figure out like `LISTEN`/`NOTIFY`
though, and I'm not clear whether `database/sql` could ever become a
fully functional driver as it might be missing some needed functionality
(e.g. subtransactions are still not supported after talking about them
for ten f*ing years [2]. However, even if it's not, the system would let
us support other fully functional packages or future major versions of
pgx (or even past ones like `pgx/v4` if there's demand).

`river/riverdriver` becomes a package as it now has types in it that
need to be referenced by driver implementations, and this would
otherwise not be possible without introducing a circular dependency.

Notably, this development branch has to use some `go.mod` `replace`
directives to demonstrate that it works correctly. If we go this
direction, we'll need to break it into chunks to release it without
them:

1. Break out changes to `river/riverdriver`. Tag and release it.

2. Break out changes to `riverdriver/river*` drivers. Have them target
   the release in (1), comment out `replace`s, then tag and release them.

3. Target the remaining River changes to the releases in (1) and (2),
   comment out `replace`s, then tag and release the top-level driver.

Unfortunately future deep incisions to drivers will require similar
gymnastics, but I don't think there's a way around it (we already have
this process except it's currently two steps instead of three). The hope
is that these will change relatively rarely, so it won't be too painful.
