Due to the recent release of Mbed CLI 2, the command line options
have been renamed to ensure good usability and harmonize with the old
tools.
These are the following changes done:
* Minimum Cmake - 3.19.0 is required
* Minimum Mbed-tools - 4.0.0 is required
* mbed-tools cmd `init` to `new`
* mbed-tools cmd `build` to `compile`
* Removed whitespaces
Rename the CMake variable expected from applications from MBED_ROOT to
MBED_PATH to be consistent with the naming used for the configuration file
(MBED_CONFIG_PATH) also expected from applications.
Directories that start with special prefixes (TARGET_, FEATURE_, COMPONENT_) are added to the build based on Mbed target configuration from targets.json instead of calling utility function mbed_add_cmake_directory_if_labels().
Aside from the core mbed-os CMake target, a number of targets have been created so they can optionally be included by application executables that require them using `target_link_libraries()`.
