Qunxin Liu 56ca435787 [subset] fix for collect_features and remove_redundant_lamngsys
previously remove_redundant_sys () is missing in harfbuzz, after

prune_features() in fonttools. This change is trying to get the same
result between harfbuzz and fonttools.

Garret Rieger 190b7a98f8 [subset] Update PairPosFormat2 subsetting to match fontTools updated subsetting (https://github.com/fonttools/fonttools/pull/2221)
- subset class def 1 against the coverage table.
- Don't re-use class 0 in class def 2.
- Ignore class 0 glyphs for the purposes of determing format 1 vs format 2 encoding for ClassDef.

Add an additional test case which demonstrates these issues.

[ot] Keep substituted Default_Ignorables (#2886)
Don’t replace Default_Ignorables with zero-width space if they are
substituted or multiplied, not just when ligated.

After this change, HarfBuzz output matches that of Uniscribe and
CoreText for the new tests.
