runtime: remove Cond
I don't think this is used anywhere right now, and it would need to be
updated to work with multithreading. So instead of fixing it, I think we
can remove it.
My original intention was to have something like this that could be used
in the machine package, but since this is in the runtime package (and
the runtime package imports the machine package on baremetal) it can't
actually be used that way.
I checked the TinyGo repo and the drivers repo, and `runtime.Cond` isn't
used anywhere except in that one test.
