Add the Sec-CH-UA-Form-Factor header

As described in https://wicg.github.io/ua-client-hints/#sec-ch-ua-form-factor

This is protected by the ClientHintsFormFactor feature flag, which is
disabled by default, so the CL introduces no new behavior. There are
still several open questions about the header, but this initial
implementation should make a suitable starting point regardless of how
those are decided.

This does not:

• Add the hint to NavigatorUAData (the spec does not require this).
• Add the hint to devtools (this can wait until more questions are answered).
