Install all optional requirements of Django

[sobolevn]

Today I faced a problem: #1601
New pytest-mypy-plugins has jinja2 as a dependency. After that we got new stubtest failures.

So, I realized that we don't have many optional Django dependencies for the runtime analysis.
For example, from extras https://github.com/django/django/blob/6a523500af5bab3e05d9be9fc1a74d986c102f1a/setup.cfg#L48:

• argon2
• bcrypt

Database drivers:

• mysqlclient: https://github.com/django/django/blob/6a523500af5bab3e05d9be9fc1a74d986c102f1a/django/db/backends/mysql/base.py
• cx_Oracle: https://github.com/django/django/blob/6a523500af5bab3e05d9be9fc1a74d986c102f1a/django/db/backends/oracle/base.py

Maybe caches? What else?

Not specifically extras, but psycopg2 or 3 will result in change the stubtest as well.

Would you prefer to go "full-extras" or to try and run multiple stubtests with different allowlists?

Multiple subtests seem better.
