Add physim tests into ctest framework

Convert physim testcases listed in
cmake_targets/autotests/test_case_list.xml into ctest. Note: Tests for
dlsim_tm4 are excluded, due to compilation issues.

CTest evaluates success based on return code: '0' = pass, non-zero =
fail. For some simulators, the return code is non-zero even when the
test is successful (as indicated by success messages in the test logs).
For some simulators, the return code is always '0'. This inconsistency
has been address in the first two commits of this MR.

To build and execute these tests:

- using cmake

    cd openairinterface5g
    mkdir build && cd build # you can also do that in cmake_targets/ran_build/build
    cmake .. -GNinja -DENABLE_PHYSIM_TESTS=ON && ninja tests
    ctest

- using build_oai: physim-related ctests are activated when PHY
  simulators are built (use build_oai with '-P' or '--phy_simulators'
  option)

    cd openairinterface5g/cmake_targets
    ./build_oai --ninja --phy_simulators
    cd ran_build/build
    ctest
