feat(hints): use all_component_info from project_description.json

Currently the component_requirements hint module does not work
as expected if the component list for a project is trimmed down.
With the new "all_component_info" dictionary info in project_description.json,
the module can produce hints even if cmake's COMPONENTS variable is
set.
