Add target HGLRC H743 WING (HG7W)

[HGLRC-T]

User description

This PR adds support for the HGLRC H743 WING flight controller board.

Key Features:

• MCU: STM32H743
• IMU: ICM42605 (SPI)
• Baro: DPS310/SPL06 (I2C)
• Mag: Supported via I2C1
• Airspeed: Dedicated ADC channel and I2C Pitot bus.
• Rangefinder: US42 support (I2C).
• OSD: MAX7456 (SPI).
• Storage: SD Card via SDIO.
• Connectivity: 6 UARTs, 3 SPI, 2 I2C buses.
• Outputs: 13 PWM outputs (supports DShot and servos).
• RX: Default set to CRSF via UART2.
• GPS: Default set to UART3.
• LED Strip: Support for WS2811 on PA0.

Default Configuration:
Optimized for fixed-wing applications with Air Mode enabled, airspeed sensor, and PINIO support for peripheral control. Blackbox logging to SD card is enabled by default.

Notes:

• The target identifier is HG7W.
• Board name: HGLRC_H743_WING.

Branch Targeting Suggestion

You've targeted the master branch with this PR. Please consider if a version branch might be more appropriate:

• maintenance-9.x - If your change is backward-compatible and won't create compatibility issues between INAV firmware and Configurator 9.x versions. This will allow your PR to be included in the next 9.x release.

• maintenance-10.x - If your change introduces compatibility requirements between firmware and configurator that would break 9.x compatibility. This is for PRs which will be included in INAV 10.x

If master is the correct target for this change, no action is needed.
