Start SmartPointers (#1679)

* Refactor to fix #1671

* Add GUI/NonGUI mode to info page

* Do not show lock config, if in non-UI mode

* Updae Changelog

* Correct includes

* Ensure key member initialization - RGB Channels

* Ensure key member initialization - WebServer

* Update RGBChannels

* Fix initialization order

* Fix key when inserting new logger in LoggerMap,
Prepare logBuffer-JSON snapshot view in LoggerManager,
Increase buffered loglines to 500

* Fix Memory leak in GrabberWrapper

* Fix Memory leak in BlackBorderProcessor

* Fix Memory leak in BlackBorderProcessor

* use ninja generator under macos

* Fix BGEffectHandler destruction

* Fix Mdns code

* Clear list after applying qDeleteAll

* Fix deletion of CecHandler

* Fix memory leak caused by wrong buffer allocation

* Remove extra pixel consistently

* Change mDNS to Qt SmartPointers

* Correct removal

* Fix usage of _width/_height (they are the output resolution, not the screen resolution)
That avoids unnecessary resizing of the output image with every transferFrame call

* Move main non Thread Objects to Smart Pointers

* Refactor Hyperion Daemon unsing smartpointers

* Correction

* Correct typos/ align text

* Fix startGrabberDispmanx

* Fix startGrabberDispmanx

* Address CodeQL finding

* Create Screen grabbers via Template

* Fix typo

* Change way of logging

* Revert change

* Address deprecation warning

* Correct auto screen grabber evaluation
