8355432: Remove CompileTask from SA

[shipilev]

A lot of SA infrastructure was added to support SA compiler replay with JDK-7088955. With JDK-8315488, we got rid from the most of it. CompileTask seems to be left behind. Nothing uses it in SA now.

Now, for Leyden, we want to massage CompileTask for better performance and reliability (JDK-8231269), and keeping CompileTask in SA would require us to implement a whole bunch of complicated, but unnecessary code.

So, it would be good to purge CompileTask from SA.

Note that I left the related vmStructs definitions, because async-profiler uses those; I think to see which methods current compiler is compiling. That use looks safe, as it polls the task from the already set up ciEnv. async-profiler would need to re-adjust after JDK-8231269 makes relevant changes in vmStructs. This PR frees us from doing the same thing in SA.
