varLib: add --drop-implied-oncurves option 
For the test, I used the Tests/varLib/data/Build.designspace as starting point, modified the 'a' glyph so that 1 on-curve point (the first one) becomes impliable for all the masters.

a99a75e8a6 [varLib/avar2] Use buildDeltaSetIndexMap() 
Also change buildDeltaSetIndexMap() to move the identity
optimization there. Update the only other callsite (COLRv2).
