[FL-2520] FW build with -Wextra (#1185)

* Fixing compiler warnings with -Wextra
* More warnings suppression, WIP
* Even more warning fixes
* Added new lines at end of text files.
* Padding fix
* Additional fixes to warnings on different build configurations; added -Wextra to default build pipeline
* Fixes for Secplus v1
* -additional warnings
* +-Wredundant-decls fixes
* FuriHal: print stack overflow task name in console
* FuriHal: add missing include
