Batch queries referencing only schema types missing imports for `pgtype` and `database/sql`

What happened?

Version: 1.15.0

Similar to #1682

batch.go fails to import "github.com/jackc/pgtype" and "database/sql" for batch queries statements when only the schema references the type.

The imports are correct when one of the parameters for the query use that specific type (e.g. WHERE bio = $1::JSONB will import the correct packages).

Relevant log output

n/a

Database schema

-- Example queries for sqlc
CREATE TABLE authors (
  id   BIGSERIAL PRIMARY KEY,
  name text      NOT NULL,
  bio  JSONB,
  published BOOLEAN
);

SQL queries

-- name: GetAuthor :batchone
SELECT bio, published FROM authors
WHERE id = $1
LIMIT 1;
