[FL-3299] furi_crash: added C2 status; added fw-version gdb command (#2638)

Browse source 
* furi_crash: added C2 status
* debug: Added "fw-version" gdb command; vscode: updated configuration to use new command
* debug: added fw-info command to debug_other session
* Toolbox: versioned structure for Version
* debug: fw-version: no longer needs an ELF file loaded
* debug: flipperversion: removed unused variable
* debug_other: print running fw version
