[FL-873] Add F5 target, lp5562 driver and api-hal-light (#347)
* Add F5 target, lp5562 driver and api-hal-light. Update api-usage, switch to F5 by default.
* API HAL: add i2c and hardware version api. Dolphin: show hardware version.
* OTP version generator and flashing utility.
* Assets script: fix code formatting
* Backport F5 changes to F4
* F4: disable insomnia, prevent damage to BLE RX path
* F5 HAL API Light: remove magic delay to fix magic BLE
* Dolphin: HW target validation on start
* invert RSSI indication in sub-1
* API HAL: rename board to body in version api
* Gpio tester: detach and release viewport on exit
