extruder: Allow configuration of pressure advance lookahead time

Browse source 
Instead of defaulting the pressure advance lookahead time to be the
same as the pressure_advance variable, allow it to be configured.
Default the new config setting (pressure_advance_lookahead_time) to
10ms.

Also, make the setting more accurate if a future move is accelerating
in the middle of the lookahead window.
