Pro 6843 context menu additional items

Summary

I need to add in palette a new item in the context menu.
This item should not open any modal but just emit an event I could listen to know user clicked on it. So I cannot use customOperations here.

I just added the possibility to pass an array of extra items to a AposDocContextMenu component.
This one can be used to call an action like we already do, or to emit a simple event when closing to the parent, like I do with palette.

It allows me to do this in palette:

          <AposDocContextMenu
            :doc="docFields.data"
            :show-edit="false"
            :additional-menu-items="[{
              label: 'aposPalette:resetPalettePosition',
              action: 'reset-position',
              emitEvent: true
            }]"
            @close="menuCloseHandler"
          />
       ...
    menuCloseHandler(_doc, action) {
      if (action === 'reset-position') {
        this.resetPosition();
      }
    }

If I pass emitEvent it will simply emit close with the action as parameter.

PRO-6843 As a user, I want to be able to move Palette so that I can see elements that might be hidden under it to the right.
