instancer: drop region if axis scalar is 0 
update VarData.VarRegionCount

also set StartCoord and EndCoord to 0 (same end result as only setting PeakCoord
to 0, but this produces less noise when inspeciting the generated XML dump)

c06c5c5087 Code clean-up of items pointed out in review. 
removed unused dicts
Remove print statement
Rename v_orig_mapping_i to v_orig_mapping. The suffix was left over from an earlier pass, when there was a mapping for the direct store and another one for the indirect store.

fixup previous commit 
even if none of the referenced regions in this VarData are dropped we may still
have to apply the scalars...

refactor and simplify instantiateItemVariationStore 
we can reuse the prune_regions method defined in varStore.py to update
the VarRegionList.

also update the counts at the end (will be done automatically on compile anyway).

instancer: enumerate fvar axis indices only once then look them up 
fvar axis tags are unique, we can compute the mapping from tag to index
once and reuse when we need them index from the tag.

instancer_test: added tests for MVAR table 
I added an MVAR table to the PartialInstancer-VF.ttx test font with made-up deltas for
OS/2.yStrikeoutSize, post.underlinePosition and post.underlineThickness.
I defined 3 regions, one with only wght, one with only wdth, and one with both wdth and wght axes.

62c98b451a instancer: share same instantiateTupleVariationStore for both gvar/cvar 
refactored code, hopefully simplifying things a bit.

for cvar/cvt we do the rounding only at the end after we have summed the scaled deltas
to avoid introducing unnecessary rounding errors.

c6006a7f8c [glyf] remove_hinting should del program from composite glyph 
Unlike simple glyphs, which always have 'program' attribute (even when empty, with no instructions)
in composite glyphs, it's the presence of 'program' attribute that determines whether
the optional WE_HAVE_INSTRUCTIONS component flag is set or not.
Thus, the trim method (with remove_hinting=True) should delete the attribute for
composite glyphs.
