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.

correctness issues.
I kept the localization functionality though it is not spec compliant. But I
filed a bug to remove it in a followup.

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.

Note that `TextControlState::BindToFrame()` may also run script if it's
called without script blocker. However, it shouldn't occur. Therefore,
we don't need to mark it `MOZ_CAN_RUN_SCRIPT`, but we should check
script blocker existence with `MOZ_ASSERT`.

The destructor of `AutoTextControlHandlingState`is marked as
`MOZ_CAN_RUN_SCRIPT`, but it's not checked at build time. And this does not
need to be created when the method does not run script. Therefore, we should
mark its constructor as `MOZ_CAN_RUN_SCRIPT` instead since it's stack only
class so that its constructor and destructor are always called from same
method.

For avoiding unnecessary copy of string buffer only for comparing setting
value and current value, especially with `nsAutoString`, this patch
creates `*Equals()` methods for every class.

Sub classes of `nsITextControlElement` are only `HTMLInputElement` and
`HTMLTextAreaElement`. And both base class is
`nsGenericHTMLFormElementWithState`. Therefore, we can make
`nsITextControlElement` inherit `nsGenericHTMLFormElementWithState` and
make `HTMLInputElement` and `HTMLTextAreaElement` inherit
`nsITextControlElement`. Then, we can get rid of a lot of QI between
`nsINode`/`nsIContent`/`Element` and `nsITextControlElement` (and note that
some of them in a hot path).
Additionally, this patch renames `nsITextControlElement` to
`mozilla::TextControlElement`.

Previously, we cache only one `TextControlState` instance to reuse. However,
`HTMLTextAreaElement` also started to allocate it in the heap rather than
a part of its instance. Therefore, we should have more room to cache the
instances for saving the allocation cost.

For allowing `TextEditor` to dispatch DOM events synchronously, we should
remove `AutoScriptBlocker` in `TextControlState::SetValue()` right now.
According to the comment around the `AutoScriptBlocker`, `PrepareEditor()`
may be called while setting value. Therefore, this patch makes
`AutoTextControlHandlingState` call it if `PrepareEditor()` is called
while handling `SetValue()` and when the top most `SetValue()` ends its job.

Currently, "input" event is fired when the `AutoScriptBlocker` in `SetValue()`
is deleted. So, for keeping same behavior, the post processing after calling
`TextEditor` methods should be done before editor dispatches "input" event.
Fortunately, `TextInputListener::OnEditActionHandled()` is a good chance to
do that. Therefore, this patch makes it notify `TextControlState` and
`AutoTextControlHandlingState`.
Note that ideally, each method of `TextEditor` should return
`NS_ERROR_OUT_OF_MEMORY` coming from
`AutoTextControlHandlingState::OnEditActionHandled()`. However, it requires
a lot of changes in editor classes, and the case is really rare since editor
does not use fallible allocation. Therefore, it must be okay to crash in
editor if `OnEditActionHandled()` returns `NS_ERROR_OUT_OF_MEMORY`.

`TextControlState::SetValue()` does 4 things.
1. Committing composition if there is and if possible.
2. Setting value with `TextEditor` if text editor and frame are available.
3. Setting value without `TextEditor` otherwise.
4. Notifying value changed.
We can split #2 and #3 from it now because `AutoTextControlHandlingState`
manages nested actions. Therefore, this patch creates
`SetValueWithTextEditor()` and `SetValueWithoutTextEditor()` which take
`AutoTextControlHandlingState`.
Depends on D51394

Currently, only `HTMLInputElement` reuses `TextControlState` instance since
`HTMLTextAreaElement` had the instance as a member rather than allocate it.
Now, all instances are allocated in the heap independently for guaranteeing
their lifetime. So, the reuse mechanism should be managed by
`TextControlState` itself.

Currently, nobody guarantees that `TextControlState` won't be deleted while
it handles something with `MOZ_CAN_RUN_SCRIPT` methods.
This patch hides its destructor (and constructor) for making only
`TextControlState` itself can delete its instances. Then, if instance owner
wants to delete it while handling action(s), the oldest `AutoHandlingState`
will delete the `TextControlState`.
