add bool type asyncmsg

[zxkmm]

also notice that if you don't use, then linker will drop it so it wont occupy space

I have no idea why it can handle bool var but can’t handle the return value of a bool func. Help wanted

it's a more weird issue and exist on other member func too. it's caused by memory issue, thanks HTotoo for finding it let's merge this one and take a deep look later
