[PM-22098] Create default collection when organization member is confirmed (#5944)

* Add RequiresDefaultCollection method to PersonalOwnershipPolicyRequirement

* Add CreateDefaultLocation feature flag to Constants.cs

* Add DefaultUserCollectionName property to OrganizationUserConfirmRequestModel with encryption attributes

* Update PersonalOwnershipPolicyRequirement instantiation in tests to use constructor with parameters instead of property assignment

* Enhance ConfirmOrganizationUserCommand to support default user collection creation. Added logic to check if a default collection is required based on organization policies and feature flags. Updated ConfirmUserAsync method signature to include an optional defaultUserCollectionName parameter. Added corresponding tests to validate the new functionality.

* Refactor Confirm method in OrganizationUsersController to use Guid parameters directly, simplifying the code. Updated ConfirmUserAsync call to include DefaultUserCollectionName from the input model.

* Move logic for handling confirmation side effects into a separate method

* Refactor PersonalOwnershipPolicyRequirement to use enum for ownership state

- Introduced PersonalOwnershipState enum to represent allowed and restricted states.
- Updated PersonalOwnershipPolicyRequirement constructor and properties to utilize the new enum.
- Modified related classes and tests to reflect changes in ownership state handling.
