Convert physims in cmake_targets/autotests/test_case_list.xml to ctest

Convert physim testcases defined in cmake_targets/autotests/test_case_list.xml
into CTest based tests. These test are activated when '-DENABLE_PHYSIM_TESTS=ON'
CMake flag is set.

Note: Tests for dlsim_tm4 are excluded, due to compilation issues.

CTest evaluates success based on return code: '0' = pass, non-zero = fail.

The following table outlines the physim executables, their success expressions
(`expr_true`), and the return codes for success (`ret_success`) and failure
(`ret_fail`). The `expr_true` is used in test_case_list.xml to check for test
results.

| test_exec     | expr_true      | ret_succ        | ret_fail          |
| ------------- | -------------- | --------------- | ----------------- |
| dlsim         | passed         | 0               | -1                |

| nr_ulsim      | PUSCH test OK  | 0 (ret)         | -1 (ret)          |

Add CMake flag "ENABLE_PHYSIM_TESTS=ON" when building OAI with "-P"
or "--phy_simulators" option. This allows physim-related ctest to
be executed from build directory.

Add dependency on coding lib for all 4G physims
