Accompanying #1028

Summary by CodeRabbit

New Features
- Added support for the TANTOF405 flight controller: complete hardware configuration with multiple accelerometer/gyro options (including LSM6D variants), barometer choices, on-screen display support, SPI flash logging, beeper, LEDs, motor/servo outputs, USB, and multiple serial/I2C/SPI interfaces.
- Provided default runtime settings for telemetry, DSHOT behavior, current/voltage metering, and other startup parameters to simplify setup.

Walkthrough

Adds a new Betaflight target header configs/TANTOF405/config.h defining MCU/board/manufacturer, enabling specific sensors and peripherals, declaring comprehensive pin and timer mappings, and setting default peripheral instances and runtime parameters (DMA, SERIALRX, I2C/SPI instances, blackbox, DSHOT, meter scales, SYSTEM_HSE_MHZ).

Changes

TANTOF405 Board Configuration

Layer / File(s)	Summary
Header and boilerplate `configs/TANTOF405/config.h`	Adds new header with `#pragma once` and file boilerplate.
Target identity and feature flags `configs/TANTOF405/config.h`	Defines `FC_TARGET_MCU`, `BOARD_NAME`, `MANUFACTURER_ID` and `USE_*` macros for accel/gyro/baro/flash/MAX7456 variants.
Pin assignments and peripheral pins `configs/TANTOF405/config.h`	Declares pins for motors/servos/beeper/PPM/LEDs/UART/I2C/SPI/ADC/USB/ESC/flash/OSD/gyro EXTI/CS and related peripheral pins.
Timer pin mapping `configs/TANTOF405/config.h`	Defines `TIMER_PIN_MAPPING` mapping timer channels to output pins and PWM indices.
Runtime defaults and instance selections `configs/TANTOF405/config.h`	Adds ADC/DMA option, `SERIALRX_UART`, I2C instance selections for MAG/BARO, default blackbox device, DSHOT defaults, meter sources/scale, `BEEPER_INVERTED`, `SYSTEM_HSE_MHZ`, and SPI instance selections for MAX7456/flash/gyro.

to be clear the lsm16 is not recommended we have been unable to get it working to a level that we would endorse it. and do these guys want a t1 target if so they need to email us
