Add fetchpriority option for link + Fix prefetch url in dev mode

Description

prefetch strategy linkInsert always has fetchpriority set to "auto" which might result into busying the browser at load time. With linkFetchPriority we can set the bundle prefetch to "low" to give an indication to the browser.

LGTM! Except for the DOMContentLoaded listener. Which if I recall we were using just to test?

Verified that this does fix the paths in dev with modulepreload, dev mode is super snappy 😄

[GrandSchtroumpf]

@thejackshelton I removed the addEventListener and verify that modulepreload href works great for dev & production now.
Using html-append or js-append with modulepreload makes first interaction in devmode much faster.
