ariza 72cbfb9059 remove empty lookup subtables
Added a variant of subset_offset_array which takes an extra arg passed to serialize_subset for this impl.
Added a new api test "test-subset-gpos" for this.

Ebrahim Byagowi a32ecc15ae
Fix collect lookups logic of FeatureVariationRecord
As "Offset to a feature table substitution table, from beginning of the FeatureVariations table."
from https://docs.microsoft.com/en-us/typography/opentype/spec/chapter2 the record should
match its sanitize logic not the reverse way.

Fixes https://crbug.com/oss-fuzz/20021 and https://crbug.com/oss-fuzz/20022

Fail serialize when map has incorrect value
fixes https://crbug.com/oss-fuzz/19956

am not super happy with the fix, guess we should do some check
before the memcpy anyway as @blueshade7 thinks also,
so let's have it or revert it when we have a better approach for the case.
