Wrong JAVA_OPTS propagation, wrong PowerShell GC logging

Merging of PR3496 introduces:

• new blocker regression
  • Wrong JAVA_OPTS propagation on JDK8 (regression) and on JDK11
    • Default JAVA_OPTS, like max heap size (xmx), xms, etc. are not propagated to JVM on bat scripts
    • set "GC_LOG=true"
    • standalone.bat
    • ->

    • it looks like some quotation bug
    • according to the jconsole - max heap size (Xmx) is not set correctly (~1.8GB), according to the cli - program.name is not set correctly (program.name = "standalone.bat -Xms64M -Xmx512M -XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=256m -Djava.net.preferIPv4Stack=true -Djboss.modules.system.pkgs=org.jboss.byteman")
• new blocker bug
  • inconsistent logging
    • "standalone.bat + jdk11 + gc enabled" creates:
      • standalone\log\gc.log
      • standalone\log\gc.log.0
    • "standalone.ps1 + jdk11 + gc enabled" creates:
      • * standalone\log\gc.log

Target release of this jira should be WF15
