RFR: 8362658: sun/security/ssl/SSLEngineImpl/* tests duplicate jvm flags [v3]

[Neha Joshi]

> In this PR we have updated the code to remove the duplicate call and ensure JVM flags are added only once.
> 
> ### ISSUE :- 
> In the test case --> ProcessTools.createTestJavaProcessBuilder(Utils.addTestJavaOpts("SSLEngineKeyLimit", "p", args[1], args[2]));
>     
> -> Before executing ProcessTools.createTestJavaProcessBuilder() we are calling  ---> Utils.addTestJavaOpts() which internally call prependTestJavaOpts();
> 
>>   public static String[] addTestJavaOpts(String... userArgs) {
>>         return prependTestJavaOpts(userArgs);
>>     }
> 
> -> Then again inside ProcessTools.createTestJavaProcessBuilder() method we are calling Utils.prependTestJavaOpts()
> 
>> public static ProcessBuilder createTestJavaProcessBuilder(String... command) {
>>         return createJavaProcessBuilder(Utils.prependTestJavaOpts(command));
>>     }
> 
> 
> Calling Utils.prependTestJavaOpts() twice leads to duplicate JVM flags (This method call-> getTestJavaOpts() the main reason for duplication and below is the implementation for the same. )
> 
>> public static String[] getTestJavaOpts() {
>>         List<String> opts = new ArrayList<String>();
>>         Collections.addAll(opts, safeSplitString(VM_OPTIONS));
>>         Collections.addAll(opts, safeSplitString(JAVA_OPTIONS));
>>         return opts.toArray(new String[0]);
>>     }
