Cross-scheme initiator should result in `Sec-Fetch-Site: cross-site`. 

Before this CL, IsSameSite helper function in
services/network/sec_header_helpers.cc would only compare |initiator|'s
and |target_origin|'s hosts, which meant that a request with:
  - initiator = http://foo.example.com
  - target = https://foo.example.com
would be sent with:
  Sec-Fetch-Site: same-site

After this CL, IsSameSite also compares schemes (but not ports) to match
Site Isolation's notion of a site and so the request above will use:
  Sec-Fetch-Site: cross-site
