Add CMake module for automatically discovering test cases from a CMake target

[ghost]

Description

I have written a CMake module along with a helper cmake file with function munit_discover_tests that could be used to automatically discovering test case from any CMake test target that uses Munit for unit testing, just like gtest_dicover_tests in GoogleTest CMake module in this gist.

It uses a post-build command to run <Munit test executable> --list to get list of all tests in the executable and then writes add_test command on each of them in an include file that is included by CTest whenever CTest runs.

munit_discover_tests has CMake parameters for all command-line flags in Munit except --help & --color auto|always|never, as well as an EXTRA_ARGS parameter for accomodating future changes in Munit CLI.
