Add test function for the SE050

[sosthene-nitrokey]

This PR adds a test function for the SE050 inside of the admin app.
This functionality is optional. It adds a new generic parameter for the Admin App that can either be an Se050 or the unit () type (default for backwards compatibility).

The SE050 test does:

• Return SE050 firmware version
• Return SE050 available memory
• Test most of the functionality and report progress, so that any we can know where errors happen.

The test starts with a factory-reset of the device.

Corresponding nitropy update: Nitrokey/pynitrokey#423

For some reason the test also causes a hard fault in the FIDO tests that follow when run with nitropy.

The hard fault has been solved by Nitrokey/nitrokey-3-firmware#332

Looks good. Maybe some code could be moved into a separate module to reduce the number of cfgs.

TODO

• Move SE050 tests to the SE050 backend so that it can be in the same firmware as the RNG backend.
