PHPStan\dumpType could support dumping more than one thing

# Feature request

I keep trying to use it like `var_dump` and reflexively passing multiple args to it only to get `Function PHPStan\dumpType invoked with 2 parameters, 1 required.` in the output. 

I hope it's not a huge thing to loop over `...$value` instead of just accepting `$value`, but if it is then feel free to ignore me :)
