This will make it easier to e.g. now exclude Edge Legacy when testing against
jQuery 4.x.

Closes gh-1936

That upgrade makes UI pass the whole test suite without a single jQuery Migrate
warning. 🎉

jQuery >=3.2 doesn't include scrollbars in `.height()`, this commit switches
it to `.innerHeight()` which does so in jQuery >=3.3. In  jQuery 3.2 it doesn't
either so include scrollbars in innerHeight, add it back.

Using `.innerHeight()` instead of `.height()` should be fine as menu doesn't
define padding styles.

Closes gh-1929

jQuery >=3.4.0 uses a special focus/blur handler pair
needed to fix various issues with checkboxes/radio buttons
as well as being able to pass data in focus triggers.
However, this leaves dummy focus & blur events if any of these
events were ever listened to at a particular element. There's not
a lot UI can do to fix this so we now just skip these handlers for
data comparisons in tests.

jQuery 3.2 & newer have a different animation logic and the animated elements
width/height differ from the starting ones even at the beginning of the
animation. The point of the assertions checking that they're identical was
to ensure bug #5245 is fixed; that issue manifested by a big jump to half the
element size. To test for that, it's enough to check that the first obtained
values are close to the original ones.

This makes effects tests pass in all supported jQuery versions.

Ref #5245

jQuery 3.2 incorrectly handle scrollbars in WebKit/Blink-based browsers.
This is fixed in version 3.3, see jquery/jquery#3589.
As the data here comes from jQuery directly and the changes to fix it
are non-trivial: jquery/jquery#3656, just accept
that scrollbar data in this jQuery version is inaccurate.

jQueries older than 1.11 or 2.1 were leaving a timer in the queue which could
then influence other tests.

This helps fix issues that make tooltip tests sometimes fail when run against
jQuery 3.2 or newer due to timing differences.

Details:
* Add the `moduleAfterEach` function ensuring no timers are running.
* Attach this function via `common.testWidget`.
* Attach this function to most test suites.
* Add a tooltip test helper cleaning up leftover timers.
* Rename legacy `setup`/`teardown` hooks to `beforeEach`/`afterEach`.

This is necessary to catch all possible warnings that the test files
may trigger.

The jQuery Simulate & jQuery Color updates are needed for compatibility
with jQuery master, a future jQuery 4.

jQuery positional selectors () have been deprecated in
[jQuery 3.4.0](https://blog.jquery.com/2019/04/10/jquery-3-4-0-released/)
and they'll be removed in jQuery 4.0.0. This PR removes their usage.

Most of the changes were possible without changing public API. However,
dropping `:even` usage required a change to the
[`header` option](https://api.jqueryui.com/accordion/#option-header)
of the accordion widget. I made it an optional function; this will need
to be documented.

The polyfill for `.even()` & `.odd()` is added for jQuery <3.5.0. There was
no usage of the :odd selector in the code but the `.odd()` method is also
polyfilled for completeness.

Closes gh-1904

Closes gh-1905

`.disableSelection()` was deprecated in v1.9:

The term for "Today" in Danish is "I dag" not "Idag". This is a common misspelling in the Danish language.

Summary of the changes:

* Build: Add jQuery 3.2.0-3.4.1 to versions UI can be tested against
* Build: Load jQuery & Migrate via HTTPS
* Build: Add package-lock.json to .gitignore
* Build: Update jQuery Migrate from 3.0.0 to 3.1.0
* Build: Allow to run tests against jQuery 3.x-git
* Build: Fix formatting according to JSCS rules
* Build: Disable JSCS for the inlined jQuery Color
* All: Switch from $.isArray to Array.isArray (jQuery.isArray will be
  removed in jQuery 4.0)
* All: Switch from `$.isFunction( x )` to `typeof x === "function"`
  (jQuery.isFunction will be removed in jQuery 4.0)
* All: Inline jQuery.isWindow as it'll be removed in jQuery 4.0
* Effects: Fix a timing issue in a variable declaration. Previously,
  a jQuery object was created, chained & assigned to a variable that
  was then accessed in a callback used inside of this chained
  definition. Due to a timing difference in when the callback fired for
  the first time in latest jQuery master, it was being called before
  the variable was defined.
* Tests: Make dialog & draggable unit tests less strict (newest jQuery
  returns fractional results in some cases, making comparisons fail when
  there's a tiny difference)
* All: Migrate from $.trim to bare String.prototype.trim (jQuery.trim
  will be deprecated in jQuery 3.5)

Fixes #15195
Closes gh-1820

The old logic worked when all widgets of the same type used the same
event namespace. However, now that each instance has its own namespace,
we cannot use `_on()` for shared event handlers.
