stm32: add new device package

[deadprogram]

This PR switches all references to device/stm32 over to the tinygo.org/x/device package repo location.

Got past the original error, but now hit a different one:

tinygo build -size short -o ./build/test.hex -target=nucleo-wl55jc ./examples/sx126x/lora_rxtx/
error: Linking globals named 'WWDG_IRQHandler': symbol multiply defined!

I am able to reproduce this on my local machine as well with the latest dev build.

@aykevl can you please help out here?

I think export has been executed multiple times.
Is there something that needs to be changed in tinygo?

line 197

//export WWDG_IRQHandler
func interruptWWDG() {
	callHandlers(IRQ_WWDG)
}

@deadprogram my guess is that you still have a device/stm32 import somewhere. You could remove src/device/stm32 to check for this.

I had removed that directory from my local TinyGo (TINYGOROOT) install even before that error.

Huh. Weird. It is defined in two packages: tinygo.org/x/device/stm32 and vendor/tinygo.org/x/device/stm32. That's not something that should happen.

This might be intended behavior of the Go toolchain (go list). In which case I would really need to rethink how to implement this feature.
