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):

Currently config-override.h is included at the end of this file.

[subset] fix for collect_features and remove_redundant_lamngsys
...
previously remove_redundant_sys () is missing in harfbuzz, after
redundant langsys removal, some features are removed as well in
prune_features() in fonttools. This change is trying to get the same
result between harfbuzz and fonttools.

optimize recurse_lookups in Context/ChainContext
glyph closure, only the glyphs that the parent lookup

the lookup.

[subset] optimize glyph closure method: step1
...
Previous GSUB glyph closure is done by recursively visiting
all reachable lookup tables that apply to any glyphs in the
current/input glyph set, but actually only the glyphs that
the parent lookup can apply the recursion to can participate
in recursing the lookup. This is step 1 for glyph closure
optimization:
1. Add stack of currently active glyph set pointers into hb_closure_context_t
2. Update closure() method in simple GSUB tables to use
this stack in order not to change current glyph set at different stages
of recursion
3. Add function may_have_non_1to1() to GSUB tables

[subset] Update PairPosFormat2 subsetting to match fontTools updated subsetting ( https://github.com/fonttools/fonttools/pull/2221 )
...
- subset class def 1 against the coverage table.
- Don't re-use class 0 in class def 2.
- Ignore class 0 glyphs for the purposes of determing format 1 vs format 2 encoding for ClassDef.
Add an additional test case which demonstrates these issues.

[buffer] Fix order of HB_INTERNAL HB_DISCARD
...
Sucks that has to be specified in this order. But that is what it is for now.
Was only exhibiting problem on C++>=17 since that's when the [[nodiscard]]
was introduced.

[buffer] Implement output_glyph() in terms of replace_glyphs(0,1)
...
To my surprise, saves ~20kb in my build (non-size-optimized) build.
The output_glyph() method is never used in the fast paths, so doesn't
matter if is not fully optimized for the special case it is.
