[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

+ * - data1 (1-bits) have then a '0' pulse length of ca. 4000us
+ * - syncPost after dataPtr has a '0' pulse length of ca. 16000us

+ * LaCrosse TX 433 Mhz Temperature and Humidity Sensors.
+ * - Tested: TX-7U and TX-6U (Temperature only)
+ * - Not Tested but should work: TX-3, TX-4
+ * - also TFA Dostmann 30.3120.90 sensor (for e.g. 35.1018.06 (WS-9015) station)
+ * - also TFA Dostmann 30.3121 sensor
+ * Protocol Documentation: http://www.f6fbb.org/domo/sensors/tx3_th.php
+ * Message is 44 bits, 11 x 4 bit nybbles:
+ *    [00] [cnt = 10] [type] [addr] [addr + parity] [v1] [v2] [v3] [iv1] [iv2] [check]
+ * Notes:
+ * - Zero Pulses are longer (1,400 uS High, 1,000 uS Low) = 2,400 uS
+ * - One Pulses are shorter (  550 uS High, 1,000 uS Low) = 1,600 uS
+ * - Sensor id changes when the battery is changed
+ * - Primary Value are BCD with one decimal place: vvv = 12.3
+ * - Secondary value is integer only intval = 12, seems to be a repeat of primary
+ *   This may actually be an additional data check because the 4 bit checksum
+ *   and parity bit is  pretty week at detecting errors.
+ * - Temperature is in Celsius with 50.0 added (to handle negative values)
+ * - Humidity values appear to be integer precision, decimal always 0.
+ * - There is a 4 bit checksum and a parity bit covering the three digit value
+ * - Parity check for TX-3 and TX-4 might be different.
+ * - Msg sent with one repeat after 30 mS
+ * - Temperature and humidity are sent as separate messages
+ * - Frequency for each sensor may be could be off by as much as 50-75 khz
+ * - LaCrosse Sensors in other frequency ranges (915 Mhz) use FSK not OOK
+ *   so they can't be decoded by rtl_433 currently.
+ * - Temperature and Humidity are sent in different messages bursts.
