When the GFE issues a 413 error due to excessively long request headers, also send a Clear-Site-Data: "cookies" response header, but only if the portion of the cookie header we have is greater than a certain length.

For full context, see b/181849166.

It ended up being a bit unfortunately gnarly to get access to the incomplete request headers in the HEADERS_TOO_LONG cases, requiring changes to the base BalsaFrame, HTTP/2, and QUIC, but I think the resulting state is not too unreasonable. That said, I'm open to suggestions of a better approach.
