[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

# Flipper Zero as CMSIS DAP/DAP Link
Flipper Zero as a [Free-DAP](https://github.com/ataradov/free-dap) based SWD\JTAG debugger. Free-DAP is a free and open source firmware implementation of the [CMSIS-DAP](https://www.keil.com/pack/doc/CMSIS_Dev/DAP/html/index.html) debugger.
## Protocols
SWD, JTAG , CMSIS-DAP v1 (18 KiB/s), CMSIS-DAP v2 (46 KiB/s), VCP (USB-UART).
WinUSB for driverless installation for Windows 8 and above.
## Usage
### VSCode + Cortex-Debug
Set `"device": "cmsis-dap"`

{
"name": "Attach (DAP)",
"cwd": "${workspaceFolder}",
"executable": "./build/firmware.elf",
"request": "attach",
"type": "cortex-debug",
"servertype": "openocd",

"./debug/stm32wbx.cfg",
],
"postAttachCommands": [
"source debug/flipperapps.py",
],
},
```
</details>
### OpenOCD
Use `interface/cmsis-dap.cfg`. You will need OpenOCD v0.11.0.
Additional commands:
* `cmsis_dap_backend hid` for CMSIS-DAP v1 protocol.
* `cmsis_dap_backend usb_bulk` for CMSIS-DAP v2 protocol.
* `cmsis_dap_serial DAP_Oyevoxo` use DAP-Link running on Flipper named `Oyevoxo`.
* `cmsis-dap cmd 81` - reboot connected DAP-Link.

openocd -f interface/cmsis-dap.cfg -c "cmsis_dap_backend usb_bulk" -f debug/stm32wbx.cfg -c init -c "program build/latest/firmware.bin reset exit 0x8000000"
```

<summary>Reboot connected DAP-Link on Flipper named Oyevoxo</summary>
```
openocd -f interface/cmsis-dap.cfg -c "cmsis_dap_serial DAP_Oyevoxo" -c "transport select swd" -c "adapter speed 4000000" -c init -c "cmsis-dap cmd 81" -c "exit"
```
</details>
### PlatformIO
Use `debug_tool = cmsis-dap` and `upload_protocol = cmsis-dap`. [Documentation](https://docs.platformio.org/en/latest/plus/debug-tools/cmsis-dap.html#debugging-tool-cmsis-dap). Remember that Windows 8 and above do not require drivers.
