[subset] Add source_blob as a hb_subset_context_t field (#2203)
So no more double sanitizing source table.

Ebrahim Byagowi ff984ed3cd Use multiplication to avoid undefined behaviour per clang
Newer versions of MSVC with /we4146 don't like putting negative sign behind a
unsigned number as https://github.com/harfbuzz/harfbuzz/pull/2069
That however have made https://crbug.com/1050424 this complain:
  src/hb-ot-color-sbix-table.hh:304:28: runtime error: negation of -2147483648 cannot be represented in type 'int';
                                        cast to an unsigned type to negate this value to itself
which apparently can be fixed using this change.

Let's see if this won't make another ubsan complain!

This patch fixes the error.

Khaled Hosny c9796d15e1 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.
