hgweb: make fctx.annotate a separated function so it could be wrapped

This patch moves "fctx.annotate" used by the "annotate" webcommand, along
with the diffopts to a separated function which takes a ui and a fctx.
So it could be replaced by other implementations which don't want to replace
the core "fctx.annotate" directly.
