Translate's pagetranslation.uls module needs to override the action
that happens after language code is set. Currently it uses setlang
url parameter, which (no longer) works with Special:MyLanguage.
After this patch, it can use mw.uls.setLanguage and does not need
to reimplement it's functionality.
Turned mw.uls.changeLanguage into simple utility that calls
location.reload when the promise is resolved.

This refactor will allow us to separate these two functions so that
the modernized version of Vector can avoid loading the compact
language list.
Changes:
* `options` is now optional to the CompactInterlanguageList constructor
The max value is already defined in
CompactInterlanguageList.prototype.init
* this.interlanguageList is now initialized inside the constructor
Previously calling CompactInterlanguageList.prototype.createSelector
or getCompactList before calling init would throw an exception.
This will be important in I0518ecdf402ebf5eb6bad2c430f6462322c0d8e1 when
the responsibilities of wiring up the button and compacting the languages
is separated.

Follows-up c578db02 and ea671b1f, which I thought removed
all code relating to the old async EventLogging method.
I didn't notice this UI code at the time, because I only took a
single pass over the code to find dead code. Now that that code
is gone, it is clear that the UI code is also redundant.
The mw.track() and logEvent() methods don't track the Beacon API's
async fetches, which also isn't needed, since the loss of browser
context upon navigation doesn't abort background beacons.
The loading of the EL library itself is already ensured via a
dependency so we already know there won't be an async fetch for
that.
What that leaves is some portion of older browsers in which a
EventLogging falls back to 'new Image'. This is basically just
IE 11 per <https://caniuse.com/beacon>, and for those some portion
of events will have been lost since EventLogging removed support
two+ years ago for tracking those fallback fetches via a Promise
(because of the perf issues caused by what the removed code here
was able to do).

As a precursor to incorporating a new language switcher in the new
version of Vector I'd like to improve the performance of loading
the switcher.
It seems most code can be deferred until the language selector
button is clicked.
This shaves around 30kb of resources off the critical path for
most users. There's potential here for a positive performance
impact so we should follow up the deployment by checking the
associated performance graphs to see if there's improvement.
Note, if the compact personal links feature is enabled
there is no performance saving for now. This will be addressed in follow
ups.

These modules are always loaded together. There is no need to load
them in separate ResourceLoader modules

When mw.uls.getFrequentLanguageList() is requested sometimes
the language that is a redirect returned causing other codebases (like Wikibase)
to show an invalid language to the user.

The createCompactList() function runs synchronously during the
module execution burst. Due to it visually changing the page, I
won't defer it with rIC for the time being, although that should
be considered for the future. For this commit, I'm trying to make
it fit the budget of <50ms because ULS is currently usually taking
80ms-180ms on desktop (MacBook/Chrome CPU/4), and that's during
batch execution with other modules as well, thus freezing the
UI thread for much longer than that.
constructor:
* Remove needless clone of jQuery object.
Use $foo instead of $( $foo ).
* Remove creation of 'interlanguageList' and 'compactList' objects
that are immediately removed and re-created by init().
init/getInterlanguageList:
* Use the HTMLElement.lang and HTMLAnchorElement.href properties
directly instead of the DOM getAttribute().
This means stores a full url instead of a relative url, which
should help avoid other bugs in the future.
* Remove needless jQuery() constructor and jQuery.text() call.
Use Node.textContent directly instead.
* Use HTMLElement#querySelectorAll instead of jQuery#find().
init/getCompactList/../filterByLangsInText:
* Avoid jQuery() constructor and jQuery.attr(),
use the HTMLElement.lang property directly.
* Avoid jQuery() selector, call querySelectorAll directly.
init/getCompactList/../getCommonLanguages/../getFrequentLanguageList:
* Avoid temporary array copies from concat() and function overhead
with forEach() and filter().
Instead, keep only a single array, and iterate it once.
init/getCompactList/../filterByBadges (~10m -> ~0.5ms):
* Use one query via $(), instead of two queries $()+find().
* Use $.map() directly instead of map()+fakejQueryObject+toArray().
* Use querySelector(One) for the child instead of $()+find().
* Use HTMLElement.lang property directly.
init/hideOriginal (~5m -> ~0.8ms):
* Use querySelectorAll() directly instead of jQuery find().
* Set HTMLElement.style directly instead of jQuery() css().
init/render/addTrigger:
* Use createElement() and direct properties instead of $(), addClass(),
prop() and text().
* The mw.msg() calls use text() and jqueryMsg#parser which is
expensive.
Use plain() for 'ext-uls-compact-link-info', which doesn't need parsing.
Keep text() for the other message, and document why.
init/listen:
* Use async Deferred#then() instead of sometimes-sync Deferred#done().

'mw' are '$' are globals, always have been, and aren't going
anywhere. They're every bit as real as their longer versions.
If anything, the longer ones are less "real" or 'stable" because
they're not used internally by RL and easier to accidentally
replace or override. For anecdotes and history, see 91f950d6b0.

Notable changes:
* First query global preferences to detect if global language setting
is in use. If there is no global language setting, or if GlobalPreferences
extension is not installed, it will fall back to changing the language
as usual. If global language setting is found, it will add an override
instead.
* If a local override is added, the undo tooltip is different and links to
the global preferences page. The task design shows mw.notify style popup
located on a bottom right corner (LTR). I deviate from the design and
re-use the old undo tooltip with a different message instead, for
consistency. The message is chosen depending on whether local storage
value `uls-gp` is set to '1' (set in mw.uls.changeLanguage).
* I removed one use of deprecated mediawiki.api.options module. One other
use still remains.
* I changed tooltip text generation from html acrobatics to use
mw.message.parseDom. Because of that I also had to move the click handler
to avoid buildup of click handlers.
* In message documentation fixed acronym -> autonym.

* In mw.uls.addPreviousLanguage, jQuery.map was used for what is
essentially filtering, not mapping. Filtering was used to remove
one element from array. Use Array.prototype.splice instead.
* In mw.uls.getFrequentLanguageList, replace:
- jQuery.each with Array.prototype.forEach
- jQuery.inArray with Array.prototype.indexOf
- jQuery.grep with Array.prototype.filter

Enable several of the ULS modules so they can be used in a mobile context,
in particular by the Translate Extension
Changes:
* Create a ext.uls.common module that can be loaded safely on mobile
* Only add the ext.uls.init entry point module on desktop (ensured by
the use of targets). On mobile it has no impact other than to increase
the amount of bytes shipped to users.
* Note various modules have not been enabled for mobile usage.
