Message:

Resource Hints: Allow passing custom attributes to resource hints.

[37920] introduced resource hints that allow browsers to prefetch specific pages or render them in the background. With this change, the as, crossorigin, pr, and type attributes can be passed in addition to the URLs/hosts.

Props peterwilsoncc, swissspidy.
Fixes #38121.
