[subset] Raise the bar in new vs old table size
...
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.

Fix sbix glyph extents
...
* The ‘height’ needs to be negated since the API returns “distance from
top to bottom side”.
* Similarly, the ‘y_offset‘ needs to be added to the height to get the
‘y_bearing’, since sbix’s offset is “the point in the glyph relative
to its lower-left corner which corresponds to the origin” while
‘y_bearing’ is the “top side of glyph from origin”.
With these changes the sbix glyph metrics return values similar to other
tables, as they were otherwise unusable.
