Add Conan recipe for VTD simulator

[cassava]

Previously, we relied on a user-installed instance of VTD and used the environment variable VTD_ROOT to help us find this instance. By providing users a way to create a local Conan package, we achieve a better integration with cloe-launch and the rest of the build system.

I had some trouble installing and using cloe-launch. Let's have a look whether that's in scope of this PR or not.

[cassava]

@clssn, Neither pipx nor pip can install as editable a package that contains a pyproject.toml file. Delete the file, and everything works fine. This is a problem with PEP 517, supposedly.

See: pypa/pipx#151

[cassava]

I resolved all noted issues and rebased the branch.

[clssn]

Cancelling obsolete review.
