Add CMakelists (#321)

* Add CMakelists

The CMake support is still in development. For more information, see mbed-os/cmake/README.md

* CMake: Add required Mbed OS component

Mbed OS has multiple targets that can be linked to as required.

* CMake: Add support for BLE_LED and sync with master

This commit syncs the feature-cmake branch with master and adds CMake
support for the BLE_LED example project as the BLE_Button example
project is being removed.

* CMake: Use renamed Mbed CMake targets component

They are now prefixed with "mbed-" instead of "mbed-os-"

* CMake: Perform toolchain and language setup

* CMake: BLE button removal

* CMake: Call mbed_set_post_build API for setting post build operations

- Update CMake minimum version required from 3.18.2 to 3.19.0
- Replace mbed-os source path MBED_ROOT with MBED_PATH in CMakeLists.txt

* add CMake support for BLE_Advertising example
