[11u] (urgent) RFR (XS) 8265718: Build failure after JDK-8258414 11u backport

[Aleksey Shipilev]

Current jdk11u fastdebug build fails with:

/home/shade/trunks/jdk-updates-jdk11u-dev/src/hotspot/share/jfr/leakprofiler/checkpoint/objectSampleCheckpoint.cpp: 
In static member function 'static void ObjectSampleCheckpoint::on_rotation(const ObjectSampler*)':
/home/shade/trunks/jdk-updates-jdk11u-dev/src/hotspot/share/jfr/leakprofiler/checkpoint/objectSampleCheckpoint.cpp:298:14: 
error: 'JfrJavaSupport' has not been declared
   298 | DEBUG_ONLY(JfrJavaSupport::check_java_thread_in_native(thread);)
       | ^~~~~~~~~~~~~~
/home/shade/trunks/jdk-updates-jdk11u-dev/src/hotspot/share/utilities/macros.hpp:393:26: note: in

       | ^~~~

Fix:
