[POC] Render QR codes client-side, using a library instead of Shlink's URL

[acelaya]

This is a proof of concept to provide a way to generate customized short URL QR codes, without depending on Shlink's /{short-code}/qr-code public URL, which is a liability and getting deprecated, to eventually be removed in Shlink 5.0.0

This aims to provide the same capabilities, but without having to hit Shlink's server at all, and with the eventual ability to locally store the default QR code configuration in the apps using ShlinkWebComponent.

The missing code coverage requires running tests in an actual browser to properly test it. This is being addressed separately.
