Move Language subclasses to includes/

Depending on which namespace we want these classes to have after
T166010 they could either stay in includes/languages/ (plural) in
their own MediaWiki\Languages\-namespace dedicated to Language
subclasses, or they could go in into a subdirectory like
`includes/language/languages/` if we want to keep them in the same
top-level namespace as other Language classes and services, but in
a more nested namespace.

For now, I've made the smaller change and kept the Language subclasses
in their own directory directly under includes/, not nested further.

Bug: T225756
