Add an option to buffer expensive JITServer compilations

This commit adds an option `TR_DisableJITServerBufferedExpensiveCompilations`, which can be enabled using `-Xjit:disableJITServerBufferedExpensiveCompilations` command line option. The option is used by OpenJ9 to enable buffering of expensive local compilations on JITServer client. Signed-off-by: Dmitry Ten <Dmitry.Ten@ibm.com>
