Introduce a new attribute to externally_connectable,

accepts_tls_channel_id.  When sites are allowed to connect to an
extension, and specify include_tls_channel_id in their
chrome.runtime.connect or chrome.runtime.sendMessage options,
and the extension sets the accepts_tls_channel_id attribute,
automatically annotate the TLS channel ID as an attribute of the
MessageSender given to the onConnectExternal handler.
