[release-branch.go1.22] net/http: persist header stripping across repeated redirects

When an HTTP redirect changes the host of a request, we drop
sensitive headers such as Authorization from the redirected request.
Fix a bug where a chain of redirects could result in sensitive
headers being sent to the wrong host:

  1. request to a.tld with Authorization header
  2. a.tld redirects to b.tld
  3. request to b.tld with no Authorization header
  4. b.tld redirects to b.tld
  3. request to b.tld with Authorization header restored

Thanks to Kyle Seely for reporting this issue.

Fixes #70530
For #71210
Fixes CVE-2024-45336
