fix(tvix/eval): thread Display & PartialEq through to thunk values r/4703

If a thunk is already evaluated, there are cases where due to the
memoisation implementation something might observe a value wrapped in
a thunk.

In these cases, the implementation of `Display` and `PartialEq` must
delegate to the underlying value.

Note that there are a handful of other cases like these which we need
to cover.

It is a little tricky to write integration tests for these directly,
especially as some of the open-upvalue optimisations coming down the
pipe will reduce the number of observable thunks.

One test that covers a part of this behaviour is currently
disabled (needs some more machinery), but it's being brought back in
the next commits.
