Override the target language in the parser options, so that it isn’t
looked up from the database; this lets UriLibraryTest avoid database
access. And since the Database group is no longer strictly required,
remove the statement to that effect from the phpdoc again.

- Force a content model on the title used by LuaEngineTestBase, so that
calls to getPageLanguage() won't end up hitting the DB
- Don't actually use SiteStats from SiteLibrary in unit tests. There
seem to be no test actually using this data.

All LuaEngineTestBase subclasses must be in the Database group, as far
as I can tell it can’t be avoided. (Several already are anyway.) We
can’t centrally do this in the base class anymore (needsDB() can no
longer be overridden), so just add it to the phpdoc here.

mw.loadData() allows for optimizing the loading Lua tables by requiring
only one parse and lookup. However it's often easier for people to
write/maintain bulk data in JSON rather than Lua tables.
mw.loadJsonData() has roughly the same characteristics as mw.loadData()
and it can be used on JSON content model pages in any namespace.
As noted on the linked bug report, it's possible to already implement
this by writing a wrapper Lua module that loads and parses the JSON
content. But that requires a dummy module for each JSON page, which is
just annoying and inconvenient.
Test cases are copied from the mw.loadData() ones, with a few omissions
for syntax not supported in JSON (e.g. NaN, infinity, etc.).

For the most part, it is a good idea to avoid global variables and use
`local` variables instead. Quoting from the ScopeTutorial[1], "The
general rule is to always use local variables, unless it's necessary for
every part of your program to be able to access the variable (which is
very rare)."
Wikimedia module authors have written "Module:No globals", which errors
on the use of any global variable. On the English Wikipedia, this is
used on 32% of pages (18 million). Wikidata[2] indicates that it's been
copied to 334 other wikis.
Lua itself distributes an extra named "strict.lua"[3], which is what
this is based off of. Similar to bit32.lua, this is a pure-Lua library
that can be imported/enabled with `require( "strict" )` at the top of a
module.
The two changes I made from Lua's strict is to exempt the `arg` key,
which is used internally by Scribunto, and remove `what()`, since we
don't enable access to `debug.getinfo()` for security reasons.
