Add unit tests for libexpr (#5377) * libexpr: fix builtins.split example The example was previously indicating that multiple whitespaces would be collapsed into a single captured whitespace. That isn't true and was likely a mistake when being documented initially. * Fix segfault on unitilized list when printing value Since lists are just chunks of memory the individual elements in the list might be unitilized when a programming error happens within Nix. In this case the values are null-initialized (at least with Boehm GC) and we can avoid a nullptr deref when printing them. I ran into this issue while ensuring that new expression tests would show the actual value on an assertion failure. This is unlikely to cause any runtime performance regressions as printing values is not really in the hot path (unless the repl is the primary use case). * Add operator<< for ValueTypes * Add libexpr tests This introduces tests for libexpr that evalulate various trivial Nix language expressions and primop invocations that should be good smoke tests wheter or not the implementation is behaving as expected.

Allow unit test infra to be reused across libs' tests This allows using Arbitrary "instances" defined in libstore-tests in libexpr-tests, something we will leverage in a moment.

Parse string context elements properly Prior to this change, we had a bunch of ad-hoc string manipulation code scattered around. This made it hard to figure out what data model for string contexts is. Now, we still store string contexts most of the time as encoded strings --- I was wary of the performance implications of changing that --- but whenever we parse them we do so only through the `NixStringContextElem::parse` method, which handles all cases. This creates a data type that is very similar to `DerivedPath` but: - Represents the funky `=<drvpath>` case as properly distinct from the others. - Only encodes a single output, no wildcards and no set, for the "built" case. (I would like to deprecate `=<path>`, after which we are in spitting distance of `DerivedPath` and could maybe get away with fewer types, but that is another topic for another day.)
