Add CMakePresets.json

Introduce CMakePresests.json which is a simple way to perform incremental build using cmake

New configure resets were added:
 - default: Configure compilation with default options
 - tests: Same as above but ENABLE_TESTS and SANITIZE_ADDRESS is ON

New build presets were added:
 - 5gdefault: Build the software for NR rfsimulator test
 - default: same as 5gdefault
 - 4gdefault: Build the software for LTE rfsimulator test
 - tests: build all unit tests

To configure using configuration preset:

`cmake --preset <preset_name>`

To build using a build preset:

`cmake --build --preset <preset_name>`
