mcuboot, usbx and filex integration

[tdjastrzebski]

What I’m proposing is not a problem-specific fix, but rather an idea to increase the practical value of ThreadX.

Integrate ThreadX with mcuboot. At present, mcuboot supports all major RTOSes, but unfortunately not ThreadX.

Once mcuboot supports ThreadX, implement a USB bootloader based on usbx and filex.

This combination would be a standout feature and, in my opinion, would make ThreadX an exceptionally versatile and valuable product, greatly streamlining the development of complete, professional solutions based on ThreadX.

I also believe this is relatively low-hanging fruit.
