[FL-1970, FL-1965, FL-1872, FL-1689] Python framework, Scripts and fixes (#779)

* Scripts: add flipper lib, migrate ob to flipper lib, update ob.data
* Makefile: speedup build with phony target for .d files
* FuriHal,U8G2: full MGG display support and ERC contrast tuning.
* Desktop: fix dolphin rename artifact.
* Scripts: port otp.py to flipper scripting lib.
* Scripts: add wipe and core1 flashing to flash.py, remove obsolete shell scripts
* Scripts: replace core1 flashing script with global makefile.
* Scripts: final touches and migration to python. Root Makefile for everything.

 Always flash your device in the folllowing sequence:
 
 - OTP (Only on empty MCU)
-- Core2 firmware
-- Core1 firmware
+- Core1 and Core2 firmware flashing
 - Option Bytes
 
 ## Otp flashing
 
 !!! Flashing incorrect OTP may permanently brick your device !!!
 
-Normally OTP data generated and flashed at factory.
+Normally OTP data generated and flashed at the factory.
 In case if MCU was replaced you'll need correct OTP data to be able to use companion applications.
-Use `otp.py` to generate OTP data and `flash_otp_version_*` to flash OTP zone.
+Use `otp.py` to generate and flash OTP data.
 You will need exact main board revision to genrate OTP data. It can be found on main PCB.
+Also display type, region and etc...
 
 !!! Flashing incorrect OTP may permanently brick your device !!!
 
-## Core2 flashing
+## Core1 and Core2 firmware flashing
 
-Script blindly updates FUS and Radiostack. This operation is going to corrupt bootloader and firmware.
-Reflash Core1 after Core2.

-## Core1 flashing
-
-Script compiles and flashes both bootloader and firmware.
+Main flashing sequence can be found in root `Makefile`.
+Core2 goes first, then Core1.
+Never flash FUS or you will loose your job, girlfriend and keys in secure enclave.
