Moves the page's title above the article toolbar (i.e. tabs) based
on the VectorTitleAboveTabs config option. This feature remains
off by default, but can be accessed via the query parameter `vectortitleabovetabs`.

as some configuration flags are prefixed with vector and some without.

languageinmainpageheader => vectorlanguageinmainpageheader
languagealertinsidebar => vectorlanguagealertinsidebar
titleabovetabs => vectortitleabovetabs

An issue was found in QA where certain browser/screenreader combos could not read `aria-labelledby`+`aria-label`. Instead, we avoid using `aria-labelledby` and the `label` element entirely and apply the accessible label directly to the `input`. This great simplifies our labelling and improves screenreader support, while also allowing us to hide the `label` element to reduce verbosity.
Because the `label` element is used differently in the portal menu, we use the `is-portal` variable to maintain the old markup for portal menus

Creates two new templates:
- ContentHeader.mustache containing the site header and indicators or languages
- ContentSubheader.mustache containing site tagline and conditionally indicators
This changes DOM order.
- It adds the `<header class="mw-body-header">` to all pages,
including special pages & edit pages, not just pages with the language button.
- It moves the #siteSub element (tagline) outside of the
`<div id="bodyContent">` element.
- Adds a clearfix (or margin-collapse fix) to `.vector-body`.
This changes causes a minor difference (perhaps improvement) where on special pages,
the beginning of the content, starting with the `mw-specialpage-summary` element,
was positioned closer to the page title than on regular pages.
The clearfix ensures that the height between the page title and content is consistent across all pages.

The LatestSkinVersionRequirement is problematic for various reasons:
1) It uses the "useskin" query string
parameter which may or may not refer to the correct
skin (in the case of a non-existent skin it will always come to the conclusion that
it is not modern Vector and thus must be legacy).
2) It uses the User object which may or may not be safeToLoad
depending on when called.
The feature seems redundant at this point, as we are separating code
into separate classes Vector and Vector22 and all the features only apply
to modern Vector. I suggest we remove it and use the features explicitly in the skin
intended.

an optimal change. Until we can pull out some of the language checks

This commits sets up the Table of Contents to bold the active section
when the section is scrolled.
Unfortunately, because our content does not have actual sections but
instead has a flat list of headings and paragraphs, we can't use
IntersectionObserver in the conventional way as it is optimized to find
intersections of elements that are *within* the viewport and the
callback will not reliably fire during certain scenarios (e.g. with fast
scrolling or when the headings are not currently within the viewport).
Furthermore, iterating through a list of elements and calling
`getBoundingClientRect()` can be expensive and can also cause
significant forced synchronous layouts that block the main thread.
The best compromise in terms of performance and function that I've found
is to use a combination of a throttled scroll event listener and
IntersectionObserver's ability to asyncronously find the
boundingClientRect of all elements off the main thread when `.observe`
is called which is the approach this patch takes. Although this is an
unorthodox way to use IntersectionObserver, performance profiles
recorded while holding the "down" arrow and scrolling for 10 seconds
with a 6x CPU throttle are comparable between master and this patch:

After I628435a4a, we were asserting a boolean was given because we're
extending HTMLFormField which requires a boolean value. This was safe
because GlobalPrefs would provide a boolean, but that changed with
I594f6297.
We could rework GlobalPrefs once again to ensure only a boolean is
passed in, but since HTMLLegacySkinVersionField already has special
handling around the data types, it seems to make sense to contain the
type transformation in this class.
Simply removing the Assertion is enough to prevent T296068, however
depending on when the global preference was saved (such as since MW
1.38.0-wmf.9 but before wmf.10), it's possible either a bool or a string
was saved, hence we check for both to ensure correct display.

Can be disabled via &vectorstickyheaderedit=0 or configuration
change.
This will allow us to fine tune the edit features without blocking
deploying the existing feature.

When the sticky header is visible, it has a global impact on the
scrolling UX. For example, it can undesirably overlap elements when the
user clicks on a jump link and when the user tabs through elements in
reverse order. Therefore, we need to add scroll padding to the root
element when the sticky header is enabled (when the feature flag is on
and at higher resolutions)
Known limitations:
* Scroll padding is supported by all the latest modern browsers except
for Safari [1]. This was considered an acceptable tradeoff with the
caveat that this decision may be revisited in the future as we learn
more about user interaction with the sticky header.

When looking at raw html it always looks like something is missing when
there are trailing or leading spaces on attributes.
Just move the space into the conditions and it looks better.

* In legacy Vector, menu items are now wrapped with spans. This
consistency in HTML is required for splitting Vector into two
different skins.
* Vector's portlet link items now support icons

Styling should not depend on IDs to allow us to have multiple
searches in the page.
Precursor for wiring up search in the sticky header.
This also tweaks performance metrics to track separate metrics
for the sticky header search

This is going to be forbidden going forward.
The legacy lookup and overrides are deferred
until they are actually needed to keep the constructor
cheap
