Fix a potential Http2WriteQueue overflow scenario.

This CL addresses the overflow scenario described in cl/608648082 by adding two
bytes of HPACK per-header overhead when estimating the serialized size in bytes
of a HEADERS frame. In particular, the length of a header name will be expected
to fit within 2 bytes (vs. 1 byte before), and the length of a header value
will be expected to fit within 3 bytes (vs. 2 bytes before).
