[Devtools] Removed "redirects" from NetworkRequest to use redirectSource

redirectSource was always a chain that linked to the previous redirect
and could walk the chain from request to request. NetworkManager was
setting "redirects" on the request and it was used in a few parts of the
code but NetworkRequest never exposed it for use. Since redirects is not
needed except when appending a new redirect to the chain I removed it
and walked the chain instead for those cases.
