NFC refactoring (#3050)
"A long time ago in a galaxy far, far away...." we started NFC subsystem refactoring.

Starring:

- @gornekich - NFC refactoring project lead, architect, senior developer
- @gsurkov - architect, senior developer
- @RebornedBrain - senior developer

Supporting roles:

- @skotopes, @DrZlo13, @hedger - general architecture advisors, code review
- @Astrrra, @doomwastaken, @Hellitron, @ImagineVagon333 - quality assurance

Special thanks:

@bettse, @pcunning, @nxv, @noproto, @AloneLiberty and everyone else who has been helping us all this time and contributing valuable knowledges, ideas and source code.

added DigitalSequence and PulseReader (#2070)
* added DigitalSequence to chain multiple DigitalSignals
added PulseReader for hardware assisted digital signal sampling
* added send_time option to start a signal at a specific DWT->CYCCNT value
* fixed linter errors and undone function renaming
* fixed renaming
* flagged functions in api_symbols.csv
* allow gpio field to stay uninitialized in digital_signal_prepare_arr()
* fix test cases to match (expected) implementation
* pulse_reader: build as static library
Signed-off-by: g3gg0.de <git@g3gg0.de>
* fix starting level detection in pulse_reader
* added unit test for pulse_reader
* change pulse reader test timings to 1, 10 and 100 ms
* fine tuned timings for pulse_reader test
* pulse_reader_stop now deinits GPIO as recommended by @gornekich
* ran format_py
* pulse_reader: remove from API, allow to link with faps
Signed-off-by: g3gg0.de <git@g3gg0.de>
* remove unit test for pulse_reader again
* pulse_reader: add call to set GPIO pull direction
* make structures private, add C implementation of digital_signal_update_dma()
* digital_signal/pulse_reader: allow parameters for free to be NULL
* digital_signal: show unoptimized and optimized code for digital_signal_update_dma() next to each other
* pulse_reader: further optimize assembly code
* digital_signal: reduce code complexity of digital_signal_update_dma() by only reconfiguring DMA2
* digital_signal: remove assembly code, limiting the performance but increasing portability
* added recovery if the timer already expired
* digital_signal: fix memory leak
* digital_signal: keep lock until all DMA transfers have finished
* DigitalSequence: fix issues with concatenation of same levels and spurious bit flips
* DigitalSignal: use cyclic DMA buffer for sequences
* update api_symbols.csv
* Update api_symbols.csv for f18 target
* Patches from @gornekich to fix linter warnings.
* Remove some redundant if checks
* Remove some magic numbers and reformat.
* Remove forced terminating edge.

b9a766d909 [FL-2627] Flipper applications: SDK, build and debug system (#1387)
* Added support for running applications from SD card (FAPs - Flipper Application Packages)
* Added plugin_dist target for fbt to build FAPs
* All apps of type FlipperAppType.EXTERNAL and FlipperAppType.PLUGIN are built as FAPs by default
* Updated VSCode configuration for new fbt features - re-deploy stock configuration to use them
* Added debugging support for FAPs with fbt debug & VSCode
* Added public firmware API with automated versioning
