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

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.

...
https://crbug.com/oss-fuzz/16740
This is actually an interesting thing that {h,v}mtx allocates as
much as a font pretends to have glyphs but the solution is not
that obvious as regular fonts can have less than actually containing
metrics in their {h,v}mtx. This change raises the bar to consider this
hmtx 4 byte for every glyph case.
Initially we wanted to just find things allocating crazy amount of
memory but having the assert has led to interesting findings also
so let's don't remove the assert and see what we can find elsewhere.
