[WPE] Do not use a sync IPC message to send the host FD to the web process

[Carlos Garcia Campos]

It can be sent as a web page creation parameter instead.

Not thrilled with the use of "FD" in the patch.

> Source/WebKit/UIProcess/API/wpe/PageClientImpl.h:146
> +    IPC::Attachment hostFD();

This should say "override" or "final"; applies even though the underlying function is a pure virtual. My preference is final, but it seems we have a mix in this file.

> Source/WebKit/UIProcess/API/wpe/WPEView.h:57
> +    virtual ~View() = default;

I suggest we consider just deleting this line entirely, because this is what happens if we don’t declare the destructor at all, and I think it’s elegant to just let that happen. OK this way too, though.

> Source/WebKit/UIProcess/PageClient.h:488
> +#if PLATFORM(WPE)
> +    virtual IPC::Attachment hostFD() = 0;
> +#endif

This is a messy pattern, but I suppose it’s what we are using for lots of other things above, so it’s not great for me to complain just about this one.
