Walkthrough

Adds a new board configuration header for the DREAMWORKSH743 Betaflight target, defining MCU, board/manufacturer IDs, sensor and peripheral feature flags, pin mappings, DMA/timer options, and default peripheral/instance assignments.

Changes

Cohort / File(s)	Summary
DREAMWORKSH743 Board Configuration configs/DREAMWORKSH743/config.h	New header (+~150 lines) introducing STM32H743 MCU target, board/manufacturer identifiers, USE_* feature flags (sensors, flash, OSD, beeper), motor/LED/UART/I2C/SPI/ADC pin mappings, gyro CS/EXTI/CLKIN pins, USB detect, TIMER_PIN_MAPPING, DMA options, SPI/I2C instance assignments, default device/measurement sources, and BOX/PINIO config macros.
