feat(user_ldap): Add config for partial search compatibility with ActiveDirectory

[marcelklehr]

• Resolves: Allow LDAP search users with *term* #45555

Summary

While OpenLdap can find partial matches in the middle of a value with term*, active directory does not and needs *term* for this, which OpenLDAP interprets as a literal *, however. This PR adds a config switch to add partial search support for Active Directory.
