Desc:

• adding user_content_type_identifier parameter to view was moved to adminUI, as this is where this param is declared.

• SearchForm and Data was moved to new bundle, with BC layer of class_alias

• All form types/data mappers and co. that was needed for search type to run was copied 1:1 to new bundle, as they are to generic to moved them.

• EzSystems\EzPlatformAdminUi\Search\AbstractPagerContentToDataMapper was moved to EzSystems\EzPlatformAdminUi\Pagination\Mapper\AbstractPagerContentToDataMapper; As it also handles Dashboard I would say it should not be in Search namespace from beginning.
