Add the ability to send an asynchronous IPC message where the response
will be returned in the form of a NativePromise.
The NativePromise will be rejected with the IPC error if an error occurs.
Otherwise, the value returned is the value of the IPC response. Unlike the
CompletionHandler version sendWithAsyncReply, the returned value is only
wrapped in a std::tuple if more than 1 element is returned.

The Promise is defined for each asynchronous message generated like so:
```
class WaitForTarget {
public:
    using Arguments = std::tuple<WebCore::SeekTarget>;

    static IPC::MessageName name() { return IPC::MessageName::MediaSourcePrivateRemote_WaitForTarget; }
    static constexpr bool isSync = false;
    static constexpr bool canDispatchOutOfOrder = false;
    static constexpr bool replyCanDispatchOutOfOrder = false;

    static IPC::MessageName asyncMessageReplyName() { return IPC::MessageName::MediaSourcePrivateRemote_WaitForTargetReply; }
    static constexpr auto callbackThread = WTF::CompletionHandlerCallThread::ConstructionThread;
    using ReplyArguments = std::tuple<MediaTime>;
    using Promise = WTF::NativePromise<MediaTime, IPC::Error, true>;
    explicit WaitForTarget(const WebCore::SeekTarget& target)
        : m_arguments(target)
    {
    }

    auto&& arguments()
    {
        return WTFMove(m_arguments);
    }

private:
    std::tuple<const WebCore::SeekTarget&> m_arguments;
};
```

We need to introduce the concept of NativePromise::runSynchronouslyOnTarget
in order to ensure that processing of asynchronous results is kept in order
when mixing with the sendWithAsyncReply/CompletionHandler API.
Consider the following:
```
    m_connectionToWebProcess->connection().sendWithPromisedReply(Messages::Message1, m_identifier)
    ->whenSettled(RunLoop::main(), __func__, WTFMove(completionHandler1));
    m_connectionToWebProcess->connection().sendWithAsyncReply(Messages::Message1, WTFMove(completionHandler2), m_identifier);
```

In this example, it is expected that completionHandler1 is run before
completionHandler2 (in the same order the IPC results were received)
By default a NativePromise will always dispatch a task to run the resolve/reject
callback, and so in the example above completionHandler1 would be run after
completionHandler2 as sendWithAsyncReply immediately calls the completionHandler.

By setting the NativePromise::Producer in RunSynchronouslyOnTarget mode,
it will immediately run the callback if already on the target thread.
Preserving the order of operations.
For the time being, RunSynchronouslyOnTarget is a response only to the
problem described above.
In the future we could imagine that it is up to the NativePromise consumer
to decide how the callbacks is to be run. But this is another problem for
another day.

API tests added for both IPC and NativePromise.

Reviewed by Chris Fleizach.

Converting a Position into a VisiblePosition can be very expensive, and listMarkerTextForNodeAndPosition
was doing this when it was often not needed (because the given node is not a descendant of a list item).

With this patch, we only do this work when in a list item.

This saves ~10.1k samples of 84832 total main-thread samples in a popular web email client.

virtual ImageBuffer::drawPattern() invoked GraphicsContext logic,

virtual ImageBuffer::drawConsuming() invoked GraphicsContext logic,
was overwritten by RemoteImageBufferProxy with the assumption that
the destination was remote GraphicsContext.

The polymorphism is at GraphicsContext level. Let the functions
be at that level:
- drawPattern already is
- Add virtual GraphicsContext::drawConsumingImageBufer and the real
  base implementation and Recorder::drawConsumingImageBuffer
  override.

Similar issue with ImageBuffer::draw is handled in another patch.

This is work towards making the NativeImage the only image primitive
being drawn from, where as currently also ImageBuffer is a

margin-trim for floats will be explored in the future in the working

occur we will remove the code related to it.

ApplyStyleCommand defines three enumerations, namely EPropertyLevel,
InlineStyleRemovalMode, and EAddStyledElement. This patch makes each of
these enums an enum class, narrows down the underlying type, and renames
the enum cases to address redundancy.

We also choose to default initialize the m_propertyLevel attribute of the
AppleStyleCommand class to PropertyLevel::Default through class member
initialization (rather than through explicit mem-init in _some_
constructor overloads). This is not a behavior change, but does make
construction cleaner.

This patch adjusts the JSWebAssemblyStruct::set() method so that it
takes an EncodedJSValue instead of a JSValue. This saves unnecessary
conversions between representations and eliminates potential exception
throws.

In the future the original functionality may be helpful for expanded JS
API capabilities.

This patch also makes a minor adjustment to JSWebAssemblyArray::set() to
match the struct version.

…is flakily crashing

Reviewed by Simon Fraser.

After 268146@main, CSSStyleSheet is holding a CheckedPtr to its owner node.
It seemed fine since the owner node is expected to call clearOwnerNode() on
the style sheet on disassociation.

In the case of this crash, we can see that the owner node is a HTMLLinkElement.
HTMLLinkElement was correctly calling clearOwnerNode() on destruction. However,
it was failing to do so on the old stylesheet when replacing it in
initializeStyleSheet().

Replaced the nested for loops in CDMInstanceSessionFairPlayStreamingAVFObjC::contentKeyGroupDataSourceKeys

Add a version of get() that returns std::optional for convenience.

* Source/WTF/wtf/HashMap.h:
(WTF::Y>::getOptional const):

Note that this returns std::optional<MappedType> instead of std::optional<MappedPeakType>,
making it safer to use with reference counting smart pointers. This mean it is not usable with
maps containing std::unique_ptr and similar values but for those it would not add anything over
plain get() anyway.
