Added a new JITServer interface that provides APIs for starting the JITServer. It is used by jitserver launcher to start the JITServer. This allows elimination of '-XX:StartAsJITServer' option. All the new code related to JITServer launcher is guarded with JITSERVER_SUPPORT macro. A new flag 'build_jitserver' in j9.flags has been added which translates to J9VM_BUILD_JITSERVER macro. In j9cfg.h.ftl if J9VM_BUILD_JITSERVER is defined then we define the macro JITSERVER_SUPPORT. Currently 'build_jitserver' flag is set to false on all buildspecs. Only when '--enable-jitserver' is passed to the configure.sh when building OpenJ9, 'build_jitserver' gets set to true in the buildspec being used.
