Wa language support arduino-wasm3

Describe the request

Wa is a general-purpose programming language designed for developing robustness and maintainability WebAssembly software. The wa languge support buildin arduino-wasm target.

https://github.com/wa-lang/wa

Tere is a example:

https://github.com/wa-lang/wa/tree/master/waroot/examples/arduino

import "syscall/arduino"

global LED = arduino.GetPinLED()

func init {
    arduino.PinMode(LED, 1)
    arduino.Print("凹语言(Wa)/Arduino is running ...\n")
    arduino.Print("https://wa-lang.org\n")

    for {
        arduino.DigitalWrite(LED, arduino.HIGH)
        arduino.Delay(100)
        arduino.DigitalWrite(LED, arduino.LOW)
        arduino.Delay(900)
    }
}
