Keep supporting the pref makes a lot of `click`, `auxclick` and `contextmenu`
event creators complicated (and look messy). So, let's delete it as soon as
possible.

Now, we have `nsFocusManager::GetFocusedElementStatic()` which returns focused
element if the `nsFocusManager` instance is available. Therefore, if
`nsFocusManager::GetFocusedElement()` users do not use other methods of
`nsFocusManager`, they can use `nsFocusManager::GetFocusedElementStatic()` and
make themselves simpler.
Note that some callers return early if `nsFocusManager` is not available, but
they do not return error and `nsFocusManager` instance is available in most
time of the life time of the process. Therefore, we can simply stop using the
early return.

It's a rather useless interface:
* nsITextControlFrame is only implemented by nsTextControlFrame, so we
can just use that.
* nsIFormControlFrame had very few actual functionality, mostly
scattered around:
* SetFormProperty(select) was only useful for nsTextControlFrame.
* SetFormProperty(value) was only called on file controls.
* SetFocus() did mostly nothing, or things that can be done in
ElementStateChanged instead.
There are some do_QueryFrame calls that I replaced for better checks in
font inflation and nsIFrame, but I'll adjust to preserve behavior if you
insist (it just such a somewhat-random check).

It turns out that many sites are modifying the field state immediately after a value has been autofilled, typically to format the value such as add spaces between parts of a credit card number

The C++ code change here is simply replacing an ifdef with a pref-check (and
associated reindentation for being placed in an "if"-block).
The pref is off-by-default for now, since no other browser seems to modify
these fields through mousewheel scrolling, and users seem to be surprised when
they encounter the behavior in Firefox. See discussion on the bugzilla page.
Note: now that this behavior is controlled by a pref, we don't need to have
platform-specific #ifdefs and "skip-if" test exemptions. If we decide to bring
this behavior back on certain platforms, we can do so by simply changing the
default value of the pref on those platforms.

This is needed because we want implicit width of number and text
controls be the same, but explicit width be different to account for the
spinners. See:
data:text/html,<input type="number"><br><input type="text"><br><input type="number" min="1" max="9"><br><input type="text" size="1">
For example. This patch on its own shouldn't change behavior.

Split out from the other patch for readability. This doesn't change
behavior but unifies where we store the buttons of
number/search/password inputs.

This patch makes the all `ePointerClick` event dispatcher in C++ code use
`WidgetPointerEvent` instead of `WidgetMouseEvent`.
Then, this patch also makes the all `click` event dispatcher in chrome code use
`PointerEvent` instead of `MouseEvent`. For detecting wrong trusted event
dispatching of `click` event, this patch adds assertion into `MouseEvent`.
Therefore, all chrome test dispatchers also changed to use `PointerEvent`.
Finally, this patch includes a change of a WPT. That checks the `pointerId`
caused by executing an access key. In this case, the value should be `-1`
rather than the default value `0` because Pointer Event spec defines so for
synthetic pointer events caused by non-pointing devices [1]. Chrome also
sets it to `-1` and fails [2]. Therefore, the new assertion will pass on both
Firefox and Chrome.

This fixes two problems:
1. If no radio button is checked and the first radio button is hidden, tabbing will reach the first visible radio button in the group, rather than just skipping the group.
2. If you press down arrow or up arrow and the next/previous radio button is hidden, focus will move to the next/previous visible radio button in the group, rather than doing nothing.

This doesn't change behavior on its own, but it's likely we want to make
the tab focusability more complicated in bug 1895184, and this will make
changes to this area less painful.

The root cause of issue is that the link elements have not yet adopted the
activation behavior defined in the specification. The appropriate behavior/model
for links is still under discussion, https://github.com/whatwg/html/issues/1576.
For now, we aim for making it consistent with other browsers.

The root cause of issue is that the link elements have not yet adopted the
activation behavior defined in the specification. This patch add a hacky way to
avoid link elements perform activation behavior if it has a child input element
which will perform activation behavior. This patch introduces new flags instead of
reusing the exiting ones, allowing us to uplift this patch more safely.

This seems to be a regression by bug 1824323. If we turn on
`dom.forms.datetime.others=true`, we should dispatch `MozOpenDateTimePicker`

The test case is a special case that changes focused element from a text control
to an editing host. Therefore, without a focus change, focused editor is
changed from a `TextEditor` to `HTMLEditor`. At this time, `IMEContentObserver`
needs to switch the observing target from the anonymous content if `<input>` to
children of it.
However, the editable content becomes completely changed without a focus change
in the DOM. Therefore, `IMEStateManager` needs to synthesize a fake focus move
for IME. Therefore, this patch make `IMEStateManager` recreate
`IMEContentObserver` if active one is not observing editable content for the
focused element under "current" conditions at checking it. (When
`IMEContentObserver` is being destroyed, it sends "blur" notification to IME
and the new `IMEContentObserver` instance posts "focus" notification with
all editable content data. I.e., recreating `IMEContentObserver` generates
a fake focus move from IME point of view.)
Additionally, there is the opposite case, that is, editing host of an `<input>`
whose type is not a text control may become a text control. Therefore, this
adds new WPTs to check the handler is the text editor for the text control or
the HTML editor. The tests passed on Firefox and Chrome at least.
FYI: I guess that in this case, we need to kick `focus` event listener of the
`HTMLEditor`, but anyway, users cannot change the content because it's the
case that an atomic content is the editing host. Therefore, I don't touch
about that in this patch.
