Creates tag-from-name tables from the data in Module:Lang/data so that templates can get language tags from the
same names as the {{lang}} templates get from those tags. The conversion prefers ISO 639-1 codes.
Data in these tables are used by tag_from_name() in Module:Lang
When <name> is disambiguated, will create an additional <name> entry without the dab as long as that action won't
conflict with actual undabbed names in the source.
<name> without dab is always added to the list; this rule arises because of the three Marwari language code/name pairs:
mwr: Marwari -– not dabbed
these will not have dedabbed entries because of mwr
rwr: Marwari (India)
mve: Marwari (Pakistan)
These all share the same base name so there will not not be an dedabbed entry:
["yaka"] = "axk", -- this would be wrong for two of these languages
["yaka (central african republic)"] = "axk",
["yaka (congo)"] = "iyx",
["yaka (democratic republic of congo)"] = "yaf",
Say that we find "axk". It has a dab so we add the dabbed form to rev_lang_table{}. Then we look in
dedabbed_names_list{} to see if ["yaka"] is already there. It's not, so we add this:
["yaka"] = "axk",
Later we find "yaf". It has a dab so we add the dabbed form to rev_lang_table{}. Then we look in
dedabbed_names_list{} to see if ["yaka"] is already there. It is, so that means that more than one language
code could create an dedabbed language name key; there can be only one. Because ["yaka"] is already in the
dedabbed_names_list{} table we unset the ["yaka"] entry to empty string:
["yaka"] = '',
later we find "iyx" and add it to rev_lang_table{}. We look in dedabbed_names_list{} and find ["yaka"] has been
unset to empty string so do nothing.
When done adding names/codes to rev_lang_table{}, spin through dedabbed_names_list{} and add all non-empty-string
name/code pairs to rev_lang_table{}.
This does not catch things like overrides ["pa"] = "Punjabi" and ["pnb"] = "Punjabi". "pa" and "pnb" are not
synonyms but because the names are the same, will be treated like synonyms ("pnb" promotes to "pa"). To avoid
this, disambiguate the override: ["pnb"] = {"Punjabi"} -> ["pnb"] = {"Punjabi (Western)"}
