CLEANUP: mux-h2: Remove the h1 parser state from the h2 stream

Since the h2 multiplexer no longer relies on the legacy HTTP representation, and
uses exclusively the HTX, the H1 parser state (h1m) is no longer used by the h2
streams. Thus it can be removed.

This patch may be backported as far as 2.1.
