* ufbt: added "dolphin_ext" target (expects "external" subfolder in cwd with dolphin assets); cleaned up unused code * ufbt: codestyle fixes * scripts: fixed style according to ruff linter * scripts: additional cleanup & codestyle fixes * github: pass target hw code when installing local SDK with ufbt * ufbt: added error message for missing folder in dolphin builder * scripts: more linter fixes * sdk: added flipper_format_stream; ufbt: support for --extra-define * fbt: reduced amount of global defines * scripts, fbt: rearranged imports Co-authored-by: Aleksandr Kutuzov <alleteam@gmail.com>
