Introduce an Ldap factory in the authentication plugin

[laoneo]

Summary of Changes

Introduces an Ldap factory in the authentication plugin for better testing capability. The existing test is moved to the integration test suite as it is not a unit test. A new unit test class is added as well and some smaller code cleanup like camel case variables.

This should only be considered after #39624 got merged.

Testing Instructions

Is covered by unit and integration test.

@laoneo Could you include the configuration and documentation changes in #38775 ? The ldap tests are also moved to Integration there.

[laoneo]

Was not aware of #38775. This one should be merged first, and then I will adapt mine as well.

[laoneo]

@tatankat can you have a look here as I merged your changes from #38775.

[tatankat]

The changes already handle some of my TODOs after my PRs are accepted, so thanks for that :)

But when I try a login, I get:
Joomla\Plugin\Authentication\Ldap\Extension\Ldap::__construct(): Argument #1 ($factory) must be of type Joomla\Plugin\Authentication\Ldap\Factory\LdapFactoryInterface, Joomla\Event\Dispatcher given, called in /var/www/html/timo/joomla-cms-composed/plugins/authentication/ldap/services/provider.php on line 42
The tests succeed however. Can the register function of the provider be tested?

[laoneo]

Somehow the changes got reverted in the provider file. Fixed that.

[tatankat]

It's working now
