Garret Rieger a08900b721 [subset] fix failing colrv0 subsetting when font has composite glyphs.
Composite glyph collection was happening along side colrv0 glyph collection which meant it was possible to miss grabbing the component glyphs for a glyph added by colrv0.

Garret Rieger c35d786397 [subset] never drop the 'pref' feature.
Never ever drop feature 'pref', even if it's empty. Harfbuzz uses it to choose the shaper for Khmer.

Qunxin Liu 56ca435787 [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.

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.

Garret Rieger 3271a7cdaa [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.

Qunxin Liu 490ef1cc23 [subset] Fix namerecord ordering
This will fix inconsistency with fontTools.
Also according to the spec, namerecords must be sorted
first by platform ID, then by platform-specific ID,
then by language ID, and then by name ID.

Qunxin Liu b6a8f5e63c [subset] CMAP table subsetting fix
Not all codepoints smaller than 0xFFFF go to cmap4 table.
Only subset codepoints existing in each table.
This will also make harfbuzz consistent with fontTools' behavior
