Arjun Balgovind 7fd5e18ef4 [File Explorer] Fix enable/disable for File Explorer PowerToy (#6883)
* Commented out enable/disable for File Explorer

* Revert UI changes

* Disable the toggles if PT is not running elevated

* Fixed compilation errors in tests

* Cleaned up preview pane code to separate thumbnail and preview panes as separate classes

* Fixed broken settings format and added elevation check and registry updated required logic. Preview Handler tested manually working, Thumbnail Enable/Disable needs to be fixed

* Updated Thumbnail enable/disable logic and added warning messages

* Update tests for File Explorer

* Fixed RegGetValue failing in Release config

* Renamed new classes

* Split wrappers for disable to work

* Modified enabled flag check to also check if user is on new settings. Fixed casing issue in powerpreview.h that caused a dialog prompt on first launch after install

* Update fontweight and margin

* Fixed release build not working

* Move UseNewSettings usage to powerpreview.cpp to avoid tests breaking. For new settings the enable check is done in constructor and for old settings it is done in enable

* Update src/core/Microsoft.PowerToys.Settings.UI/Strings/en-us/Resources.resw
