Avoid a deprecation warning in graphite2
As of graphite2 1.3.7, `gr_make_face` is deprecated in favor of
`gr_make_face_with_ops`. It's a one-liner to port over to using it.
This is potentially a compatibility break since I'm not sure when the
`with_ops` API was added, but the minimum version of graphite2 that's
supported by Harfbuzz doesn't seem to be documented anywhere anyway.

Avoid undefined-behavior
If a struct had (because it's a union) sizeof that is larger than the null_size,
we were providing only null_size bytes for its Null object. We know we'd never
access beyond that, but is undefined-behavior nonetheless according to the
standard.
The alternative fix would have required use of flexible-arrays, which are not
standard and have their own issues in various compiler. We've discussed that
extensively in the follow Mozilla issue (currently locked; I've asked that it
be opened):

[sanitize] change max ops to track number of bytes processed.
Counting bytes as the operations is likely to be a better proxy for how
much work processing the table will cost vs. the current approach of
counting the number of sub-objects.
This should allow checks for max features, max scripts, etc. to be removed.
I tested this change against the full collection of fonts at https://github.com/google/fonts
and a max ops factor of 3 was sufficient to successfully sanitize all of them.

hb-config: Include config-override earlier
Currently config-override.h is included at the end of this file. This caused a problem for me while undefing HB_DISABLE_DEPRECATED, namely HB_IF_NOT_DEPRECATED was defined before actual undef took place and broke the whole build. I believe it would break builds for some other defines, too. Moving config-override.h include right after predefined configs is more sane and fixes all potential problems with includes.
