[FL-1587] RFID: Clock for emulation timer from antenna (#622) 
* RFID: pull antenna down when emulating
* Rfid: fixed HID emulation by adding zero pulse every 4 bits
* Rfid: HID emulation fixed with DSP based FSK oscillator.
* Rfid: receive 125KHz clock for emulation timer from antenna and comparator
* Rfid: commented unused variable
* Firmware: rollback changes in f6.
* Add F7 target based on F6.
* F7/F6: update cube projects, apply changes to the targets, update linker scripts with correct RAM start values.
* FuriHal: RFID init routine.
* Scripts: update OTP tool for v11 board

* @brief STM32WB55xx devices vector table GCC toolchain.
* This module performs:
* - Set the initial SP
* - Set the initial PC == Reset_Handler,
* - Set the vector table entries with the exceptions ISR address
* - Branches to main in the C library (which eventually
* calls main()).
* After Reset the Cortex-M4 processor is in Thread mode,
* priority is Privileged, and the Stack is set to Main.
