`InputEvent.getTargetRanges()` can be used only when event type is
`beforeinput`. So, it may be used for feature detection of `beforeinput`
event because Chrome does not implement `onbeforeinput` event handler attribute.
Therefore, this patch makes it behind the pref for `beforeinput` event.

If user disables clipboard events, it means that they don't want to expose
clipboard data to web apps even if web apps cannot handle "paste" operation.
Therefore, they must not want to leak clipboard data with `InputEvent.data`
and `InputEvent.dataTransfer`.
This patch makes `InputEvent::GetData()` and `InputEvent::GetDataTransfer()`
returns empty string or new `DataTransfer` object which has only empty string
if:
- They are called by content JS.
- The event is a trusted event.
- `inputType` value is `insertFromPaste` or `insertFromPasteAsQuotation`.
The reason why we don't return null for both is, Input Events spec declares
`data` or `dataTransfer` shouldn't be null in the `inputType` values. And
the reason why we don't return empty `DataTransfer` is, web apps may expect
at least one data is stored in non-null `dataTransfer` value.

InputEvent.dataTransfer is declared by Input Events Level 1 and Level 2 (i.e.,
not UI Events). It's necessary for "beforeinput" event on contenteditable
elements because of with some InputEvent.inputType values on contenteditable,
InputEvent.dataTransfer is used instead of InputEvent.data.
According to the Chrome's behavior, if InputEvent.dataTransfer is created by
web apps, the DataTransfer object is mutable. Otherwise, i.e., the event
represents user input, the DataTransfer object is read only. We should follow
this behavior.
This is enabled by default.

InputEvent.data notifies web apps of inserting/inserted text with "beforeinput"
and "input" events. So, this is important especially for "beforeinput" event
listeners. That's the reason why we need to support this before implementing
"beforeinput" event.
This patch adds it into InputEvent and make it enabled by default.

This patch implements InputType.inputType which is declared by Input Events.
The attribute has already been implemented by Chrome and Safari. Chrome
implements Input Events Level 1, but Safari implements Input Events Level 2.
Difference between them is only whether it supports "insertFromComposition",
"deleteByComposition" and "deleteCompositionText". This patch makes the
level switchable with pref and takes Level 1 by default because Level 2 is
still unstable around event order with composition events.
For reducing string copy cost at dispatching "input" event, this patch
makes EditorInternalInputEvent store valid input-type as enum class,
EditorInputType and resolves it to string value when
dom::InputEvent::GetInputType() is called. Note that the reason why
this patch names the enum class as EditorInputType is, there is InputType
enum class already for avoiding conflict the name, this appends "Editor"
prefix because "input" and "beforeinput" events are fired only when an
editor has focus.
