[subset] never drop the 'pref' feature.

[subset] fix for collect_features and remove_redundant_lamngsys
...
previously remove_redundant_sys () is missing in harfbuzz, after
redundant langsys removal, some features are removed as well in
prune_features() in fonttools. This change is trying to get the same
result between harfbuzz and fonttools.

[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.

[subset] Remove redundant langys from Amiri test font.

FontTools removes these when subsetting but harfbuzz does not yet support redundant langsys removal. So this gets the Amiri tests passing for now.

[subset] Avoid incorrectly dropping cmap for NotoColorEmoji.ttf
...
NotoColorEmoji.ttf uses two cmap subtables
Format 14 | Platform ID 0 | Platform Encoding ID 5
Format 12 | Platform ID 3 | Platform Encoding ID 10
This combination results in the cmap table being dropped during subsetting despite being valid/required.
