[Webkit/Blink] Paste From Word's conflict with the paste filter

[Piotrek Koszuliński]

On Webkit and Blink paste filter is set to semantic-content by default.

It means that every external paste will be stripped from classes and styles. And this means that PFW's options like PFWKeepStyles stop working.

We could require adjusting paste filter's options with code like:

editor.on( 'instanceReady', function( evt ) {
    if ( editor.pasteFilter )
        editor.pasteFilter.allow( '*(*)[*]' );
} );

But this basically disables the paste filter which we need on Webkit and Blink for external pasting due to the awful mess that these browsers do in HTML.

So the only solution I can think of now is to disable the paste filter if PFW was executed for that paste.

We initially had this problem in #12256.

It makes some sense. For pasting content from Word, pasteFromWord plugin is the filter and the second filtering is no needed.
