Anas Nashif 7a5ff13703 tests: allow unsupported tests to be skipped Instead of completely excluding those tests, mark them as skipped and provide an noop function that marks the test as skipped where test is not supported.

Protection tests
#################################

Overview
********
This test case verifies that protection is provided
against the following security issues:

* Write to read-only data.
* Write to text.
* Execute from data.
* Execute from stack.
* Execute from heap.

Building and Running
********************

This project can be built and executed as follows:


.. zephyr-app-commands::
   :zephyr-app: tests/kernel/mem_protect/protection
   :board: <board name>
   :goals: run
   :compact:

Connect the board to your host computer using the USB port.
Flash the generated zephyr.bin on the board.
Reset the board.
