script: Implement parsing of Link HTTP headers (#39052)

Browse source 
The Link HTTP header can do the same as link elements,
in that they can preload/prefetch/etc... This implements
the basics of header parsing and hooks it up for preload.

Note that we use a new nom-rfc8288 crate that implements
the parsing behavior. However, that crate is too strict
in that empty attributes (;; as part of the header) are
discarded and resulting in a parsing failure. Therefore,
we use its lenient parsing mode.

Part of #35035
