usb-gadget: remove usb-gadget and add configuration filetizen_8.0_m2_releasetizen_7.0_m2_releasesubmit/tizen/20220525.001052accepted/tizen/unified/20220526.144424accepted/tizen/8.0/unified/20231005.094506accepted/tizen/7.0/unified/hotfix/20221116.110417accepted/tizen/7.0/unified/20221110.063018tizen_8.0tizen_7.0_hotfixaccepted/tizen_unifiedaccepted/tizen_8.0_unifiedaccepted/tizen_7.0_unified_hotfix

The actual operation of usb-gadget is no more hal dependent. Instead,
the deviced is now in charge of running usb-gadget. The hal backend
has changed to provide only target specific usb-gadget configurations.
If there is no target specific configurations, deviced runs usb-gadget
with default configurations.
