Transplant jmh test Ring.java from Loom

changes:

1. Add jmh dependencies in pom.xml

        <dependencies>
            <dependency>
                <groupId>org.openjdk.jmh</groupId>
                <artifactId>jmh-core</artifactId>
                <version>1.23</version>
            </dependency>
            <dependency>
                <groupId>org.openjdk.jmh</groupId>
                <artifactId>jmh-generator-annprocess</artifactId>
                <version>1.23</version>
            </dependency>
        </dependencies>

2. Altered the Method for Starting Workers:

   • In the Loom version, the startAll() method was using Thread.startVirtualThread(w); to start virtual threads.
   • In the Kona version, in the same method I use Thread.ofVirtual().scheduler(Executors.newSingleThreadExecutor()).start(w); to start the virtual threads as well.

3. Modified Channel Creation:

   • In the Loom version, the getChannel() method used the enhanced switch expression syntax:

     return switch(stackFrame) {
     ...
     default -> throw new RuntimeException("Illegal stack parameter value: "+ stackFrame +" (allowed: 1,2,4,8)");
     };

   • In the Kona version, I changed it back to the conventional switch statement since the arrow syntax used in “switch” only can be complied in jdk 14 or other later version.

     switch (stackFrame) {
     ...
     default:
      throw new RuntimeException("Illegal stack parameter value: " + stackFrame + " (allowed: 1,2,4,8)");
     }

@HangerLIN I suppose you also find that this PR contains so many commits.

The target branch is KonaFiber instead of master. You may need to submit a new PR.
