Add a python interface (`revng.profile`) for interacting with the rev.ng
infrastructure as a whole; either through the CLI (`CLIProject`) or the
GraphQL API (`DaemonProject`).
Package revng's python code in two wheels: `revng` and `revng_internal`.
The revng wheel contains the
`revng.{pipeline_description,model,tupletree}` modules, while the
`revng_internal` one everything under `revng.internal`.
