As well as getting an invoker's popover target, we need to be able to do the reverse: get a popover's invokers.
We can already do this when the popovertarget content attribute is set to a string id using the dependent ids map.
However, the popover target can also be explicitly set to a DOM element using the .popoverTargetElement WebIDL attribute.
For this, we need a new map which maps from target elements instead of target ids.
RelatedAccIterator has also been updated to use this map.
DocAccessible::QueueCacheUpdateForDependentRelations had to be updated as well.
Rather than duplicating logic, RelatedAccIterator has been taught how to optionally return all relations and QueueCacheUpdateForDependentRelations now uses RelatedAccIterator.

This is consistent with other browsers and thus more web compatible.
In particular, it makes infinite scroll work correctly on YouTube (e.g. when scrolling with screen readers), which didn't work previously.

We have more readable and faster versions (that just omit the namespace
arg).
Mostly done via sed, with a couple helpers to use the faster lookups
where possible.

There is an issue that when the element is hidden because its ancestor has 'content-visibility:hidden', it still appears in the accessibility tree.
Depending on CSS Containment Spec (https://www.w3.org/TR/css-contain-2/#cv-a11y),
it should be omitted from the accessibility tree.
This change fixes the issue above.
The approach is not to create the node in accessibility tree if the element has any ancestor specified with 'content-visibility:hidden'.
This patch can be tested such as:
(1) Check if the accessibility tree is created correctly
./mach test accessible/tests/browser/tree/browser_css_content_visibility.js
(2) Check if the accessibility tree is updated correctly
./mach test accessible/tests/browser/e10s/browser_treeupdate_csscontentvisibility.js

HTMLSelectEventListener changes are needed, since currently that code works somewhat by accident given that
mTime often contains totally bogus values, like PR_IntervalNow(). Those changes then reveal issues also in
browser_editAddressDialog.js.

This doesn't change behavior, but clarifies a bit the naming to match
the scrollIntoView() API. Also makes the name generic (rather than
Top/Left/etc), since for scrollIntoView we want to make the axes be
logical.
That will be done in bug 1789464 (probably via an extra ScrollFlag).

In terms of the C++ code, this patch does basically one thing, which is
allowing creating option / optgroup accessibles without a frame for
comboboxes, and tracking mutations like layout does.
It seems this should be straight-forward, but handling mutations got a
bit complicated. We don't want to forcibly re-create accessibles, so we
want to re-use the PruneOrInsertSubtree logic that ContentInserted uses.
But determining whether we need to create the accessible requires
having flushed styles, so I added a ScheduleAccessibilitySubtreeUpdate
API to trigger that from WillRefresh once style and layout are
up-to-date.
The rest of the test updates should be sort of straight-forward. They
reflect two changes:
* <option> accessibles are leaves now (so they don't have text
children). Note that we still have the right native name and so on,
using the same logic we use to render the label.
* In 1proc tests, the focus no longer goes to the <option>, and uses
the same code-path that e10s does (moving focus to a <menulist> in
the parent process). Since that wasn't easy to test for (afaict) and
we have browser tests to cover that
(browser_treeupdate_select_dropdown.js, etc), I've decided to just
remove the tests that relied on the previous code-path, as they were
testing for a codepath that users weren't hitting anyways.
I've tested this with JAWS and Orca and behavior seems unchanged to my
knowledge.

Renaming the function makes it clear that it only deals with in-process ancestors, which is an important distinction for Fission.
A11y is the only consumer of this and it only cares about in-process ancestors in this case (OOP stuff is handled elsewhere), so the functionality doesn't need to change.
Since a11y is the only consumer, move this into the a11y code.

`nsIPresShell::ScrollAxis` can be used anywhere and it's used by some
utils actually. So, it should be in `mozilla` namespace and perhaps,
`PresShellForwards.h` is a good place to move it rather than creating
new header file.

Per the discussion in:

They should be CamelCase, and that's what most of them already do. This converts
the rest, which are a few.
For the ones that already used `e` or `k` prefixes, I've mostly done:
for file in $(rg Type::e layout | cut -d : -f 1 | sort | uniq); do sed -i 's#Type::e#Type::#g' $file; done
For the ones that used uppercase, I've removed the prefix if it was already in
the type name, and turn them into CamelCase.

This patch moves some `enum` in `nsIPresShell` which are in public scope into
`mozilla` namespace and change them as `enum class`es.
Unfortunately, only "where to scroll" enum is just defines constants of
percentages of scroll destination. Therefore, this patch makes only them
as `static const`.

Moved mozilla::WidgetMosueEventBase::buttonType in MouseEvents.h to mozilla::MouseButton in EventForwards.h, and mozilla::WidgetMouseEventBase::buttonsFlag to mozilla::MouseButtonsFlag so that any referer in header files do not need to include MouseEvents.h only for referring them. Instead, they just need to include EventForwards.h. Now when MouseEvents.h is changed, the rebuild speed becomes faster.
