The tests need to run with certain environment variables set that only
cmake really knows and that differ between stages. Cmake could just set
the variables directly when running the tests and benchmarks, but that
would leave no good way to manually run a single benchmark. So cmake
generates some stage-specific scripts instead that set the required
environment variables.
Previously, those scripts were sourced directly by the individual
`run_*` scripts, so the env scripts of different stages would overwrite
each other. This PR changes the setup so they can instead be generated
next to each other. This also simplifies the `run_*` scripts themselves
a bit, and makes `tests/bench/build` less of a hack.
This PR changes all `lean-toolchain` to use relative toolchain paths
instead of `lean4` and `lean4-stage0` identifiers, which removes the
need for manually linking toolchains via Elan.
After this PR, at least Elan 4.2.0 and 0.0.224 of the Lean VS Code
extension will be needed to edit core.

This PR adds a module resolution procedure to Lake to disambiguate
modules that are defined in multiple packages.
On an `import`, Lake will now check if multiple packages within the
workspace define the module. If so, it will verify that modules have
sufficiently similar definitions (i.e., artifacts with the same content
hashes). If not, Lake will report an error.
This verification is currently only done for direct imports. Transitive
imports are not checked for consistency. An overhaul of transitive
imports will come later.
This PR adds a test replicating Kim's diamond dependency example.
The top-level package, `D`, depends on two intermediate packages, `B`
and `C`, which each require semantically different versions of another
package, `A`. The portion of `A` that `B` and `C` publicly use is
unchanged across the versions, but they both privately make use of
changed API. Currently, this causes a version clash. This will be made
to work without error later this quarter.
