[PATCH 06/10] command.py: add resolve option for generateTargetsTree API

[Dongxiao Xu <dongxiao.xu@intel.com>]

Currently we have generateTargetsTree API, which is used to get
dependency information. However in that tree, there will be
"virtual/xxx" in depends fields. Therefore we add the resolve option
to replace it with its real providers.

Besides, for packages that provided by multiple recipes, we will find
their preverred provider.
