Basic input sequences: relative order or duplicates does not matter here (but the end of the self test displays
them sorted and deduplicated), but codes must be valid and belong to only one of the two sequences).

Any missing language code will be checked with mw.language.new(code):isRTL(), which is costly in
loaded resources (it can only check 20 languages at most including the content language).

So it is best to map all languages that are the most likely to be used, as well as all 4-letters script codes
from ISO 15924 (that can be used in recognized suffixes) that have a predefined default direction, such that
it is excluding only special script codes ('-root', '-true', '-zinh', '-zxxx', '-zyyy', '-zzzz') and the range
of 50 script codes reserved for private use ('-qaaa', ..., '-qaaz', '-qaba', ..., '-qabx').

The list of supported ISO 15924 script codes below is complete up to the 2025-01-06 update (see
https://www.unicode.org/iso15924/codechanges.html).

Note that if a language+script variant uses another direction than the default for the script, it may still
be overridden explicitly (script subtags are checked only after checking full tags, so 'en-latn-rtl' could be
defined with a rtl direction, independantly of the default direction for '-latn', and some language-specific
variants for '-tfng' may also be defined as rtl instead of the default script direction).
