Introduce support for the VML syntax for pasting images

[godai78]

📝 Provide a description of the new feature

As mentioned here: #2493 (comment) there is no support for pasting images embedded in the content using the VML Markup syntax like this one:

<v:shape><v:imagedata src="...."/></v:shape>

It would be beneficial to introduce handling this kind of syntax into CKEditor 5, as it was in CKEditor 4 (as mentioned in the cited comment): https://github.com/ckeditor/ckeditor4/blob/5380706bb4ceb6092dadb2b7067d6c14efec6b26/plugins/pastefromword/filter/default.js#L368

CKEditor 4 already researched it and handles this case, so if we'd decide to work on it, we could adapt the solution to CKEditor 5.

i'm not sure if my problem is the same issue as written here.

i'm using the Simple Upload Adapter and when I paste a text with images from word to the editor the upload adapter throw an error says the image can't be upload and shows this message error:

Symfony\Component\Mime\Exception\InvalidArgumentException: The "" file does not exist or is not readable. in file /vendor/symfony/mime/FileinfoMimeTypeGuesser.php on line 50

it's my request when I paste the image with text:

array:1 [
  "upload" => Illuminate\Http\UploadedFile {#1635
    -test: false
    -originalName: "image.png"
    -mimeType: "application/octet-stream"
    -error: 1
    #hashName: null
    path: ""
    filename: ""
    basename: ""
    pathname: ""
    extension: ""
    realPath: "/web/public"

    size: false

    type: false
    writable: false
    readable: false
    executable: false
    file: false
    dir: false
    link: false
  }
]

And this is my request pasting only the image copied from word:

array:1 [
  "upload" => Illuminate\Http\UploadedFile {#1635
    -test: false
    -originalName: "image.png"
    -mimeType: "image/png"
    -error: 0
    #hashName: null
    path: "/tmp"
    filename: "phpDWQoCd"
    basename: "phpDWQoCd"
    pathname: "/tmp/phpDWQoCd"
    extension: ""
    realPath: "/tmp/phpDWQoCd"

  }
