[FL-3174] Dolphin builder in ufbt; minor ufbt/fbt improvements (#2601)
* 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
