I have experimented with a new approach for embedding psiphon in
7fc0bcd97c.
It seems the build is still building and the experiment is still
running. With the new approach, we're now vendoring less dependencies,
which hopefully puts us in the right track to, one day, import
Psiphon as a normal Go dependency.
I'll make sure to report to the Psiphon team what is currently
preventing us from importing their ClientLibrary directly.
This work is part of https://github.com/ooni/probe/issues/1894.
As part of running the update, I run `go get -u -v ./...`, which
led to go-cmp also being updated in the process.

## Description
This PR contains a set of changes to move important interfaces and data types into the `./internal/model` package.
The criteria for including an interface or data type in here is roughly that the type should be important and used by several packages. We are especially interested to move more interfaces here to increase modularity.
An additional side effect is that, by reading this package, one should be able to understand more quickly how different parts of the codebase interact with each other.
This is what I want to move in `internal/model`:
- [x] most important interfaces from `internal/netxlite`
- [x] everything that was previously part of `internal/engine/model`
- [x] mocks from `internal/netxlite/mocks` should also be moved in here as a subpackage
This branch adds support for running:
1. `go-libtor` on mobile.
2. the tor provided by the desktop app via the `OONI_TOR_BINARY` environment variable.
