Remove unnecessary files

Remove unnecessary files

[Issue#]    N/A
[Problem]   Unnecessary files are remaind.
[Cause]     Setting UI guide was changed.
            "Web application setting" menu had a lot of menus like more details, listview, allow list and so all.
            However new "Web application setting" menu UX doesn't use old menu anymore.
[Solution]  Removed source files(*.cpp, *.h) of settings and not used images.
            1. webapp-common is deprecated.
            - As web application and native application need to show common menu UX,
              owner of "Web application details" menu is moved to setting team.
              deleted : webapp-common/popup.cpp,
                        webapp-common/popup.h
                        webapp-common/ug.cpp,
                        webapp-common/ug.webapp-common-efl.include,
                        webapp-common/util.h,
                        webapp-common/view.cpp,
                        webapp-common/view.h,
                        webapp-common/whitelistview.cpp,
                        webapp-common/whitelistview.h,
                        webapp-common/whiteuriview.cpp,
                        webapp-common/whiteuriview.h
            2. Only support "Web application permission" menu(show and edit W3C permission)
            - As requirment of customer(Orange), only support edit menu of W3C permission.
              Without this W3C permission edit menu, user cannot control decision of allow/deny
              which is made during application runtime with permission popup.
              (Only case of user selection allow/deny with checking "Remember preference" is shown in the menu)
              As new UX concept(only needs permission edit menu) other deprecated source code is removed.
              deleted : webapp-detail/advancedview.cpp,
                        webapp-detail/advancedview.h,

                        webapp-detail/permview.h,
                        webapp-detail/tizen_feature.cpp,

                        webapp-detail/view.cpp,
                        webapp-detail/view.h
            3. Clean-up source and resource regarding support WAC
              deleted : webapp-detail/wac_feature.cpp
                        webapp-detail/wac_feature.h,
