Remove unsupported parameters by the unified gesture detector from Gesture Configuration.

There are some parameters in the Gesture Configuration which are
no longer used for unified gesture detector:
max_radius_;
min_flick_speed_squared_
min_rail_break_velocity_
min_scroll_delta_squared_
min_touch_down_duration_in_seconds_for_click_
rail_break_proportion_
rail_start_proportion_
scroll_prediction_seconds_
points_buffered_for_velocity_
