Tests for language and base direction

[afs]

Tests for SPARQL 1.2 lang changes and base direction.

Related to: w3c/sparql-query#172

Current state: the draft tests are about the functions and do not involve results that include literals with base direction, which is an area the RDF-Star WG has yet to get to.

I believe literals with base direction are supported now: https://w3c.github.io/rdf-concepts/spec/#dfn-dir-lang-string
There's also support in SPARQL/JSON via its:dir: https://w3c.github.io/sparql-results-json/spec/#select-bindings
I guess we can include corresponding tests for them?

Yes - whether they go under "result set" or "dir lang string" TBD.

If you are happy to approve this PR, I can follow up with one with result tests.

At first glance, the test look good, but I don't have an implementation yet to fully confirm yet (working on it).
But if you want to merge this asap, I'm definitely ok with it.

OK - I'll take an approval as confirming process has been followed.

(More generally, as RDF-WG creates tests, putting them in as a reasonable attempt, and changing on feedback, maybe more helpful to emerging implementations at the moment.)

+1 I have no run the tests yet but I think we can meege them and do focused follow ups if needed. Thank you for doing this work!
