M59 Merge of 'Improve canonicalization of mailto url path components'

The canonicalization of the path component of mailto urls is too lax,
leading to information disclosure and possible command injection attacks
against mail clients. To fix this, we percent-encode more characters in
the path component of mailto urls, matching other Firefox/IE/Edge.

The original land of this patch (via 2817213002) omitted an update to
layout tests.
