samples/microkernel: add test for private tasks

This adds unit test for microkernel private tasks.
The code piggybacks to the public task test (by
including the same source file), so any updates to
the test will be applied to both.

Note that the prj.mdef are different for both tests, since
the private tasks test move the tasks inside source
code. So, both mdef files will need to be updated at
the same time.

+Title: test_task_priv
+
+Description:
+
+This test verifies that the microkernel task APIs operate as expected. This
+also verifies the mechanism to define private task objects and their usage.
+
+--------------------------------------------------------------------------------
+
+Building and Running Project:
+
+This microkernel project outputs to the console.  It can be built and executed
+on QEMU as follows:
+
+    make qemu
+
+--------------------------------------------------------------------------------
+
+Troubleshooting:
+
+Problems caused by out-dated project information can be addressed by
+issuing one of the following commands then rebuilding the project:
+
+    make clean          # discard results of previous builds
+                        # but keep existing configuration info
+or
+    make pristine       # discard results of previous builds
+                        # and restore pre-defined configuration info
+
+--------------------------------------------------------------------------------
+
+Sample Output:
+
+tc_start() - Test Microkernel Task API
