Blink and WebKit do not fire `beforeinput` event when user uses build-in
password manager and autocomplete. But the `inputType` value for this case,
`"insertReplacementText"` is defined as cancelable in the spec, and it's
actually cancelable when it's fired for correcting a word with built-in
spellchecker of them.
For making only our users' autocomplete and password manager not blocked by
web apps, we should make them not cancelable by default, but I think that we
should keep dispatching such non-cancelable `beforeinput` for conforming to
the standard unless we'd get a web-compat report for this.

This is mostly a revert of the patch in bug 1425686 that removed the old
probe, but rebased to new code locations and clang-formatted. The histogram
entry is also updated with new bug numbers and fields.
The next patch will refine some of these telemetry recording points; the patch
is split into two for easier reviewing as this part is basically what landed
originally.

This patch tries to mark root callers of `nsINode::GetSelectionRootContent()`
which calls `nsINode::GetAnonymousRootElementOfTextEditor()` as far as possible
(and reasonable).
It's used by `ContentEventHandler` so that a lot of methods of
`EventStateManager`, `ContentEventHandler`, `IMEContentObserver` which are main
users of it are also marked as `MOZ_CAN_RUN_SCRIPT`. I think that this is
reasonable.
On the other hand, it might not be reasonable to mark `IMEStateManager` methods
as `MOZ_CAN_RUN_SCRIPT` for initializing `IMEContentObserver` because
`IMEStateManager` may be able to initialize `IMEContentObserver` asynchronously
and its root callers are in XUL layout code. Therefore, this patch uses
`MOZ_CAN_RUN_SCRIPT_BOUNDARY` for `IMEStateManager` at least for now.

The issue here is that AccessibleCaret flushes layout from the middle of
the SetValue call, because it hides the caret (see the call stack in
comment 11).
That changes the placeholder-shown state because it goes from empty to
non-empty but the SetValue call from UnbindFromFrame is not supposed to
change that state (because we're in the middle of restyling).
Call OnValueChanged later, at the outer caller instead.

We don't need these macros anymore, for two reasons:

2. clang now warns for the "temporary that should have been a declaration" case.

Even in comm-central and BlueGriffon, `nsISelectionController::*ForDelete()`
are not used. Therefore, we can remove them safely.

`HTMLEditor::DeleteSelectionWithTransaction()` calls `EditorBase`'s overridden
method and handles `nsIEditor::eStrip` case. Therefore, we can rename it with
stop calling the `EditorBase::DeleteSelectionWithTransaction()`, and make it
called by `EditorBase::DeleteSelectionWithTransaction()` only when it's
necessary.
Additionally, we can make all internal method callers of editor classes always
set `nsIEditor::eNoStrip` if the instance is `TextEditor`. This must make
the code easier to understand.

This rejiggers a bit the way selection focus is handled so that focusing a
disabled form control with the mouse handles selection properly, and hides the
document selection and so on.
This matches the behavior of other browsers as far as I can tell.
Given now readonly and disabled editors behave the same, we can simplify a bit
the surrounding editor code.

`InputEventOptions` should be able to take target ranges for `beforeinput`
event. However, it requires to include `StaticRange.h` from `nsContentUtils.h`
even though most `nsContentUtils.h` users don't need it. Therefore, this patch
moves it from `nsContentUtils.h` to new header file.
And makes `nsContentUtils::DispatchInputEvent()` moves the target ranges
from `InputEventOptions` to `InternalEditorInputEvent`.

Previously, I added `Selection::mCachedRange` to save allocation cost of
`nsRange`. However, with the previous patch, we don't need the hack anymore
since ranges removed by `Selection::RemoveAllRanges()` are always kept in
the global cache of `nsRange`. Therefore, we can remove the ugly hack right
now.

For preparing to remove `nsIPlaintextEditor` interface, this patch moves
all of them to `nsIEditor`, but for avoiding bustage in comm-central, makes
`nsIPlaintextEditor` inherit `nsIEditor` for now (i.e., even with this patch,
script can access old `nsIPlaintextEditor` members with the interface.
In C++ code, this patch moves `SetWrapColumn()`, `InsertTextAsAction()`,
`InsertTextAsSubAction()` and `InsertLineBreakAsSubAction()` because
they do common things between `TextEditor` and `HTMLEditor`. On the other
hand, this does not move `TextEditor::GetTextLength()` because it's designed
only for `TextEditor`.

I made `nsContentUtils::DispatchInputEvent()` update validity of event target
before dispatching `eEditorInput` event in bug 1584963. However, this is not
enough because it updates validity only when the type of `<input>` element is
`mail`, but it's required for other types, for example, `<input required>`.
This patch reverts the hack added in bug 1584963, instead, makes
`TextControlState::SetValueWithoutTextEditor()` notifies `TextControlElement`
of value change before dispatching `eEditorInput` event because it may have made
damage to the performance if `nsContentUtils::DispatchInputEvent()` updated
**all** validity state of the event target.

If `TextControlState` does not have `TextEditor` and its `SetValue()` is called
from `SetUserInput()`, `TextControlState` itself needs to dispatch `beforeinput`
event.
If the value is modified by `beforeinput` event listener, it's intended that
`preventDefault()` is called by the web apps. However, the behavior in this
case is not mentioned by UI Events nor Input Events spec. We should just file
a spec issue instead of emulating Chrome's behavior for now because it requires
more changes, but this case must be an edge case.

This patch makes `nsContentUtils::DispatchInputEvent()` dispatch `beforeinput`
event too. And also adds `onbeforeinput` event handler which is really
important for feature detection (although Chrome has not implemented this
attribute yet: https://bugs.chromium.org/p/chromium/issues/detail?id=947408).
However, we don't implement `InputEvent.getTargetRanges()` in this bug and
implementing `beforeinput` event may hit bugs of some web apps. Therefore,
this patch disables `beforeinput` event by default even in Nightly channel.
