cli: Source "cloe_launch_env.sh" if generated

This can be generated from within the `generate()` method in
a Conan profile. A base Conan profile is provided by cloe-launch,
called `cloe-launch-profile`, with the same version as cloe-launch.

This can be used as a base class for profiles that want to make
easy use of its methods.
