Add more keyboard accessories

[AltCode]

Vivaldi currently houses six keyboard accessories. One when editing any text field (the passwords accessory), and 5 when the address bar is focused ( a QR code reader, .com, and three characters commonly found in URLs: :, -, /)

I think these could be expanded further. For reference, this is what the Orion browser offers as its keyboard accessories (when the address bar is focused):

Vivaldi should have these as well, why stop at :, -, and /. Also, why limit to only having .com, this one could be customisable to any tld the user wants (in a similar fashion to the domain expansion feature on desktop.

But the most noteworthy is probably the paste accessory. Of any of the other keyboard accessories, I think this one would be the best to have; and not just when editing the address bar, but any text field. In address fields, it could even be expanded to work as a quicker way to perform paste and go.
