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):

Counting bytes as the operations is likely to be a better proxy for how

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.

optimization:

this stack in order not to change current glyph set at different stages

[buffer] Return success status from buffer ops that can fail
...
Previous error-handling philosophy was that user doesn't need to
immediately know whether operation failed. But as can be seen after
we added malloc-failing fuzzing, there's just so many places in the
code that a failure of these operations needs to be mitigated before
further operations. So I'm moving towards returning success here,
and possibly making it nodiscard.

We treat Class0 as "doesn't intersect". That's the only meaningful
interpretation. If one allos Class0 to mean "intersects", then the
intersects() result should be true iff glyphset is non-empty.

Revert back IntType out cast to signed/unsigned
...
Previous commit didn't fix the bots. Putting it back now that I
understand why I initially did the "Wide" casts. But only doing
it for out-cast this time. This causes "narrowing" warnings
whenever we are converting signed/unsigned to smaller HBUINT16
etc. But those are valuable warnings. We should address those
separately instead of ignoring.
Maybe we should start using uint16_t more liberally in the
internal subsetter function signatures then.

~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~
Enabling the extra cast operator mentioned in previous commit to see if
that fixes this case.
Again, I'd be happy to say "use 1u instead of 1" if this was universally
erred on. But since some compilers happily compile this while others
err, it would be a huge headache. Let's see...

Narrow down cast operators on IntType
...
Say for USHORT, we were implementing casts from and to unsigned.
With this change, we cast from and to uint16_t only. This allows
compiler more opportunities to catch possible narrowing issues in
the code.
It needed a couple of fixes in the codebase though, because
previously, if a USHORT was participating in arithmetic with signed
numbers, eg. "u + 1", the result would have been unsigned. With
this change, it would be signed. The correct fix is to update the
code to read "u + 1u".
That said, I think about conditionally adding back the cast
out to signed/unsigned, to facilitate better type deduction.
But I couldn't think of a real situation where that would help
with anything. So I didn't add. Here's what it was:
template <typename Type2 = hb_conditional<hb_is_signed (Type), signed, unsigned>,
hb_enable_if (sizeof (Type) < sizeof (Type2))>
operator hb_type_identity_t<Type2> () const { return v; }
