No other access in the Title class contains a `get` prefix, so this
makes the title methods consistent.

Added `categories` property in the lua title class which fetches page
categories. Analogous to getContent() which fetches page content. This
increments the expensive function count.
This enables category-specific editnotices (T85372) and other use-cases.

When modules are first loaded by `require` in package.lua, it checks
for a return value with `if res then`. If that check fails, the module
will be cached with the default value `true` at line 109, and that
value is then returned.
That check should be changed to `if res ~= nil then`, because
otherwise a module with a return value of `false` will be cached with
the value `true`.
This also necessitates a corresponding change to the check at line 93,
which is when `package.loaded` is initially checked to see if a package
has been loaded before, as that value could be `false`.

`mw.clone` is called on the global table for each new `{{#invoke:}}`,
which is a major contributor to loading times on large pages. This
change introduces various speed optimisations that make it around
15% faster:
* `recursiveClone` is declared outside of the main function, to avoid
generating a new closure each time `mw.clone` is called.
* This means `tableRefs` has to be passed as an argument to
`recursiveClone` instead of being an upvalue, which also decreases
access time.
* `recursiveClone` is only called after a `type` then `tableRefs` check
confirms a value is an unseen table, meaning it's only called when
needed, not for every key/value pair (which add noticeable overhead
when cloning large tables).
* `getmetable` is only called once, not twice, by using a local
variable.
* `tableRefs[elt]` is only accessed once, by using a ternary operator.
* Any global accesses have been replaced by local ones.

`mw.loadJsonData` in mw.lua throws an error if the input argument is
not a string. The error message should refer to the type of the input
argument `module`, not that of the variable `arg` (which is usually
undeclared, giving the type `nil`).
This also necessitates updating test `mw.loadJsonData, bad title (1)`
in CommonTests.lua, which checks for the error message if the input
is the number 0; the correct message should say "got number", not
"got nil".

In TitleLibrary::getContentInternal(), an external (interwiki) title will
fail when we try to `Parser::fetchCurrentRevisionRecordOfTitle`, but by
that time we've already tried to add it to the dependency list for the

In order to avoid misleading the caller, set some title properties to
nil for interwiki links. That value should still be falsey, but can
prevent making unwarranted assumptions about the destination of
interwiki links.

ScribuntoContent now supports content being redirects, if the underlying
ScribuntoEngine does so. For Lua, a redirect looks like:
return require [[Module:Foo]]
which also happens to be perfectly valid Lua. There is intentionally no
`#REDIRECT`-style token (like in wikitext/JavaScript/CSS) because no one
will create a page with this content except for the purposes of a
redirect.

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.
