Support trySendBlocking() Coroutines API in Kotlin/Native

trySendBlocking() is only available in Kotlin/JVM. But the implementation doesn't seem to have any JVM-specific requirements. Copying the extension function to a KMM shared module compiles just fine, only warning about InternalCoroutinesApi usage in ChannelResult:

@Throws(InterruptedException::class)
public fun <E> SendChannel<E>.trySendBlocking(element: E): ChannelResult<Unit> {
    trySend(element).onSuccess { return ChannelResult.success(Unit) }
    return runBlocking {
        val r = runCatching { send(element) }
        if (r.isSuccess) ChannelResult.success(Unit)
        else ChannelResult.closed(r.exceptionOrNull())
    }
}

Can this function be added to support Kotlin/Native?

The deprecated sendBlocking() function that functions similarly is available, but can't be replaced with trySendBlocking() as it suggests.
