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:

Before Vue/WVUI lazy loads, we have intermediate search components that
are rendered on the server and that need to be styled based on the
`autoExpandWidth` prop passed to the search component. This commit
refactors VueEnhancedSearchBox to use this class if present.
Additionaly:
* Cleanup fixmes from Id8d3bd4aa74113b91ecaf66cb58cf5625db8a302
* Replace `vector-search-box-show-thumbnail` class with
`.vector-search-box-auto-expand-width` class in Header.less now that
the class has been cached in the HTML.

In preparation for I30c670e3f195f77a27715c6b494a3088b7a55712, refactor
the search component expand behavior so that it can accomodate the new
changes in WVUI while maintaining backwards compatibility with the
status quo.
Additionally, pass/enable the `auto-expand-width` prop to the main
header's search. This will be inert until the new changes in WVUI have
landed.

Since a margin was added to adjacent sibling spans of icons (https://gerrit.wikimedia.org/r/c/mediawiki/core/+/736919), Vector icon buttons have had too much spacing. This patch removes the extra spacing defined in Vector CSS and the accidental whitespace that was included in the ULS buttons..

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.

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

Per T289724#7342741, server renders an anchor tag pointing to #p-search
into the "button-start" bucket of the sticky header.
In the future after T289718, this anchor will then acts as a button when
the search module is loaded and searchToggle executes.
* skins.vector.search was modified to accomodate instantiating multiple
search components (one in the main header and one in the sticky
header).
* searchToggle.js was modified to accept a searchToggle element as a
param which the caller can then instantiate when ideal. For the sticky
header toggle, this needs to happen *after* the search module loads.
Before then, the toggle will act as a link.
* Drops one jQuery usage from searchToggle so that it can be jQuery
free. Because the native .closest method is used, IE11 support is also
dropped. However, the script feature detects and returns early if the
API isn't available.
* Makes App.vue accept an `id` prop so that multiple instances of it can
be created.

We have many styles related to the layout and visibility of search that
are only useful in the context of the main header. Since many of these
elements have classes that will also be in the sticky header, we should
scope these rules to the main header so that we avoid an uphill battle
of styles trying to override eachother.
Additional changes:
* We previously had a mix of #p-search and .vector-search-box selectors
for the same element in the CSS. Header.less now only uses
.vector-searchbox to avoid specificity wars.
* Removed nearly all of the #p-search rules previously found on L147 -
L167 in screen.less after observing nothing relatively bad happening
when they were removed.
