meta-ide-support: A dummy recipe to install everthing for target development

Move the environment-setup script generation into a separate class and adapt
meta-toolchain to use it.

Add a new dummy target, meta-ide-support, to install an appropriately
configured script to TMPDIR and ensure all of the required packages for target
development are available.
