Fix pasting images from Firefox on Windows.

Fixes #10564.

Together with the image data Firefox sets to the clipboard an URLs list
which has a path to local temp file, created from that image.

Reading images from disk is slower + sometimes the content of the file
is wrong so for this case we prefer to read the image data directly.
