[Mobile] Better support for dragging links

Use case or problem

Currently you can drag links around on mobile, but can only use it to open the link in the current tab. Also, dragging a link from a sidebar dosen’t close the sidebar.

Proposed solution

Being able to drag links to the tab stack to open the page in a new tab would be nice. Also being able to drag notes out from the sidebars to the title (the already built in “open in current tab” drag point) or to the tab stack as well.

Current workaround (optional)

Long pressing links works to open in a new tab, but can easily be fat-fingered and annoying to accidently press something unintentionally. Also it’s slower than dragging usually (hold tap then another tap rather than hold and drag).
