[FL-3097] fbt, faploader: minimal app module implementation (#2420)
* fbt, faploader: minimal app module implementation
* faploader, libs: moved API hashtable core to flipper_application
* example: compound api
* lib: flipper_application: naming fixes, doxygen comments
* fbt: changed `requires` manifest field behavior for app extensions
* examples: refactored plugin apps; faploader: changed new API naming; fbt: changed PLUGIN app type meaning
* loader: dropped support for debug apps & plugin menus
* moved applications/plugins -> applications/external
* Restored x bit on chiplist_convert.py
* git: fixed free-dap submodule path
* pvs: updated submodule paths
* examples: example_advanced_plugins.c: removed potential memory leak on errors
* examples: example_plugins: refined requires
* fbt: not deploying app modules for debug/sample apps; extra validation for .PLUGIN-type apps
* apps: removed cdefines for external apps
* fbt: moved ext app path definition
* fbt: reworked fap_dist handling; f18: synced api_symbols.csv
* fbt: removed resources_paths for extapps
* scripts: reworked storage
* scripts: reworked runfap.py & selfupdate.py to use new api
* wip: fal runner
* fbt: moved file packaging into separate module
* scripts: storage: fixes
* scripts: storage: minor fixes for new api
* fbt: changed internal artifact storage details for external apps
* scripts: storage: additional fixes and better error reporting; examples: using APP_DATA_PATH()
* fbt, scripts: reworked launch_app to deploy plugins; moved old runfap.py to distfap.py
* fbt: extra check for plugins descriptors
* fbt: additional checks in emitter
* fbt: better info message on SDK rebuild
* scripts: removed requirements.txt
* loader: removed remnants of plugins & debug menus
* post-review fixes
