Teach planner how to estimate rows for timestamp generate_series

This provides the planner with row estimates for
generate_series(TIMESTAMP, TIMESTAMP, INTERVAL),
generate_series(TIMESTAMPTZ, TIMESTAMPTZ, INTERVAL) and
generate_series(TIMESTAMPTZ, TIMESTAMPTZ, INTERVAL, TEXT) when the input
parameter values can be estimated during planning.
