72b6102949 [instancer/L4] Fix normalizeValue for L4 solver 
Imagine a font with current min/default/max of 100,700,1000. And new
setting of 100,400,1000. The current normalizeLocation will calculate
the new location for 700 to be +.33, whereas it should calculate +.5!
This is because 400 translates to -.5, so 700 will be normalized to
-1,-.5,+1 and get +.33...

We need a special normalizeLocation that is aware of the "distance"
between min/default/max, ie. the non-normalized values. Then it will be
clear that the distance from 400 to 700 is equal to 700 to 1000, and as
such 700 should be normalized to .5, not .33... I'm still trying to
figure out the case where avar is present.

Store this distance in NormalizeAxisLimit and reach it out in the
solver.

drop oncurve if it's impliable either before OR after rounding 
ofter the rounding gives us an opportunity to make an oncurve impliable, for points that were not equidistant become so after round, so why not take it!

_getCoordinatesAndControls: make sure coords are rounded toInt() as gvar expects 
ufo2ft will no longer send varLib already-rounded master glyf tables (to give it an opportunity to compute implied oncurves on the pre-rounded coords) so when retrieving coordinates off the glyf table in order to compute gvar deltas we have to round

ttGlyphPen: drop implied before rounding, allow not to round at all 
We want to be able to compute implied oncurves both before coordinates have been rounded to integer and afterwards.
Also when ufo2ft builds interpolatable master TTFs, we want to turn off the rounding so that varLib can call dropImpliedOnCurvePoints on the un-rounded coordinates, so we need an option to disable rounding the coordinates in the ttGlyphPens

also check endPtsOfContours in dropImpliedOnCurvePoints 
as per review https://github.com/fonttools/fonttools/pull/3147#discussion_r1214708207

Also, don't do same work multiple times when dropping points from flags/endPtsOfContours arrays since these are supposed to be the same for all interpolatable glyphs

varLib: add --drop-implied-oncurves option
