Tab5 camera + other stuff (#558)

* Tab5 camera + other stuff

Tab5 camera driver - SC2356
Custom SliderBox widget - slider with plus and minus buttons + value label and snapping
Rtc Time service + rtc api
Sdk release - only include drivers built for that specific target, eg: sc2356 driver is mipi / p4 only.
No more hardcoded manual sdk cmakelists
New function to find device by compatible string match. no more static cast bool wildness when trying to match a single device (like M5Stack PaperS3 for example)

* feedback + fixes

Fixed external app user data path.
fix(gui): block app teardown until onHide() completes, preventing ELF unload racing a still-running app
added camera device type and api

* drain the snake sssem
