Make LocalisationCache a service

This removes Language::$dataCache without deprecation, because 1) I
don't know of a way to properly simulate it in the new paradigm, and 2)
I found no direct access to the member outside of the Language and
LanguageTest classes.

An earlier version of this patch (e4468a1d6b) had to be reverted
because of a massive slowdown on test runs. Based on some local testing,
this should fix the problem. Running all tests in languages is slowed
down by only around 20% instead of a factor of five, and memory usage is
actually reduced greatly (~350 MB -> ~200 MB). The slowdown is still not
great, but I assume it's par for the course for converting things to
services and is acceptable. If not, I can try to optimize further.
