SceneTable functionnalities (#25849)

* Added a Global scene count, GetAllSceneIdsInGroup and RemoveAllScenesInGroup along with their test. Fixed line endings from SceneTable.h
Added automaticall removal of scene when it can't be loaded due to number of supported cluster being reduced by OTA
Added tests for OTA with changes in max scenes number (global and per fabric)

* fixed comparison on wrong variable causing un-initialized member

* Added Isnit verification to all scene table operation requiring permanent storage access, added check on table capacity to prevent creation of table table with capacity above max

* Update src/app/clusters/scenes/SceneTableImpl.cpp

* Removed dupplicate of Deserialize for Scene Fabric Data, added test for GetAllSceneIdsInGroup for the corner case of a list of size = 0 and for BUFFER_TOO_SMALL other situations, added comments for the size of the global count in storage

* Restyled by clang-format

* Update src/app/clusters/scenes/SceneTableImpl.cpp

* Stubed Deserialize and re-implemented DeserializeAdjust to avoid duplicating code

* Apply suggestions from code review

Co-authored-by: Boris Zbarsky <bzbarsky@apple.com>

* Changed return of Stubbed Deserialize to return error if used, Changed DeserializeAdjust->Deserialize and moved adjustment to GlobalSceneCount out of Deserialize into Load function to adjust the count in the case where a failure would happen after scenes are deleted

* Update src/app/clusters/scenes/SceneTableImpl.cpp

Co-authored-by: Boris Zbarsky <bzbarsky@apple.com>

* Fixed return of load in the event of a failiure to Deserialize when deleting scenes, explicited deleted_scenes_count value on failure to deserialize

* Update src/app/clusters/scenes/SceneTableImpl.cpp

* Removed redundant returns in Load() method
