Added target for Airbot Omnibus F4 Nano v2.5 with support for blackbox (OBF4NANOBB)

Added target for Airbot Omnibus F4 Nano v2.5 with black box support. Target OBF4NANOBB

Added target for Airbot Omnibus F4 Nano v2.5

Add MK file for new Omnibus F4 Nano Target

- Refactored the current CLI based implementation of vtx_akk_hack into a new feature named: "LEGACY_SA_SUPPORT"

- Re-added the tailing byte in send frame as a possible fix for the "standard" implementation of Smart Audio, due to user reporting that turning the hack off for Unify and other "standard" SA VTX-es will result in an incorrect setting save issue (settings are only saved after unplugging and re-plugging the battery)

- This PR should be accepted with the relevant Butterflight-Configurator PR that adds the "LEGACY_SA_SUPPORT" feature to the configuration tab

- Incrementing the MSP protocol minor version to 39 and the EEPROM version is required before release

- Adding "LEGACY_SA_SUPPORT" as a feature to MSP requires this increment

* adding beeper inversion

* adding RSSI ADC pin setting for target

- It passes on though HID interface 8 channels received from TX
- Endpoints are reconfigured to support HID interface
- Potentially this can slow down SPI Flash transfer though CDC interface...
- This could be addressed by support for MSC when using SPI Flash (emulating FATFS)

Fixed indentation in feature.h

* hotfix version 103

* re-enable overclocking ability

* lowering default yaw pids and removing moron_threshold override

* removing profiles, just lowering default pids and filter values

* fix LED port and ESCSERIAL

Add Composite CDC+HID device option.

Revert "Add Composite CDC+HID device option."

Revert "Revert "Add Composite CDC+HID device option.""

 - For now disables Composite (it can be enabled, with USB_CDC_HID define)
- Modified descriptors so they are properly recognized
- Changed PID for Composite device (otherwise it doesn't work probably due to windows feature - automatically finding drivers based on those values)

Enable Composite USB HID for all F4, add PG for USB device.

Implement vtx_akk_hack cli command as a switchable feature
