RFR: 8315097: Rename createJavaProcessBuilder [v2]

[Leo Korinth]

> Rename createJavaProcessBuilder so that it is not used by mistake instead of createTestJvm.
> 
> I have used the following sed script: `find -name "*.java" | xargs -n 1 sed -i -e "s/createJavaProcessBuilder(/createJavaProcessBuilderIgnoreTestJavaOpts(/g"`
> 
> Then I have manually modified ProcessTools.java. In that file I have moved one version of createJavaProcessBuilder so that it is close to the other version. Then I have added a javadoc comment in bold telling:
> 
>    /**
>      * Create ProcessBuilder using the java launcher from the jdk to
>      * be tested.
>      *
>      * <p><b> Please observe that you likely should use
>      * createTestJvm() instead of this method because createTestJvm()
>      * will add JVM options from "test.vm.opts" and "test.java.opts"
>      * </b> and this method will not do that.
>      *
>      * @param command Arguments to pass to the java command.
>      * @return The ProcessBuilder instance representing the java command.
>      */
> 
> 
> I have used the name createJavaProcessBuilderIgnoreTestJavaOpts because of the name of Utils.prependTestJavaOpts that adds those VM flags. If you have a better name I could do a rename of the method. I kind of like that it is long and clumsy, that makes it harder to use...
> 
> I have run tier 1 testing, and I have started more exhaustive testing.
