RFR: 8262881: port JVM/DI tests from JDK-4413752 to JVM/TI

[Daniel D.Daugherty]

Add three tests from JDK-4413752 ported to JVM/TI:

- RawMonitorEnter() with SuspendThread()
  - test/hotspot/jtreg/serviceability/jvmti/SuspendWithRawMonitorEnter/SuspendWithRawMonitorEnter.java
  - test/hotspot/jtreg/serviceability/jvmti/SuspendWithRawMonitorEnter/libSuspendWithRawMonitorEnter.cpp

- ObjectMonitor enter() with SuspendThread()
  - test/hotspot/jtreg/serviceability/jvmti/SuspendWithObjectMonitorEnter/SuspendWithObjectMonitorEnter.java
  - test/hotspot/jtreg/serviceability/jvmti/SuspendWithObjectMonitorEnter/libSuspendWithObjectMonitorEnter.cpp

- ObjectMonitor wait() with SuspendThread
  - test/hotspot/jtreg/serviceability/jvmti/SuspendWithObjectMonitorWait/SuspendWithObjectMonitorWait.java
  - test/hotspot/jtreg/serviceability/jvmti/SuspendWithObjectMonitorWait/libSuspendWithObjectMonitorWait.cpp

The Java files have a transaction diagram to show what each of the
threads in the test is doing.
