feat(tvix/glue): introduce test suite for context strings r/7404

This is an additional test suite on the top of the Nix ones
for context strings matters.

It already smoked out multiple mistakes and potential bugs and non-deterministic result from the evaluator.

It uses a similar technology as the one in the tvix-eval albeit we instantiate a fully fledged evaluator
with in-memory store.

We copy the files instead of symlinking them because crates are built in
isolation, so symlinks cannot work.
