[FL-1934] Core: wipe memory after free. SubGhz: key encryption tool. (#797)

Browse Source 
* Core: wipe memory after free. RFID,iButton: fix iterator use after invalidation.

* Debug: support unix wildcards for register matching in svd, update MCU description file and minify it.

* Toolbox: getter for File in FlipperFile.

* Makefile: conditional flashing

* SubGhz: keeloq_mfcodes encryption tool.

* FuriHal: proper IV handling on CBC in crypto. SubGhz: add support for encrypted keeloq keys. Makefile: move formatting to top Makefile.

* SubGhz: rename some function names to match naming scheme.

* SubGhz: encryption tool, fix windows line endings
