add jvmLaunchers

When you need to perform some operations through a child process, it is very cumbersome and requires a lot of coding. I have an api below to simplify this process and make it elegant

Like this: The Callable event is executed by the child process (jvm)
```
JVMLauncher<Integer> launcher = JVMLaunchers.<Integer>newJvm()
.setCallable(() -> {
System.out.println("************ Compile start ***************");
TimeUnit.SECONDS.sleep(1);
System.out.println("************ Compile stop ***************");
return 1;
})
.setXms("16m")
.setXmx("16m")
.addUserjars(Collections.emptyList())
.setConsole((msg) -> System.err.println(msg))
.build();

VmFuture<Integer> out = launcher.startAndGet();
```
