[subset] speed up add_gid_and_children and adjust op limit.

Fix for fuzzer timeout: https://oss-fuzz.com/testcase-detail/5001604901240832 .
- Operation limit is per glyph, so 100,000 should still be far more than needed.
- Switches from for(...) to while(...) loop for iteration. for(...) calls it.end() which in this case triggers a complete iteration.
- Cache CompositeGlyph size in the iterator to avoid needing to recalculate it.

Fix documentation of hb_subset_flags_t defaults
...
HB_SUBSET_FLAGS_DEFAULT is 0, and hb_subset_input_create_or_fail
initializes its flags to HB_SUBSET_FLAGS_DEFAULT, so currently all flags
are set to false by default. It has been decided that future flags will
also be false by default for simplicity (using NO_ in the name if
needed). Correct and simplify the documentation for hb_subset_flags_t to
reflect this.

Construct user_data in hb_object
...
hb_object's user_data is created lazily. The previous implementation of
hb_object_set_user_data created space for the user_data but did not
actually construct it. This means that hb_user_data_array_t's lock was
not constructed. If hb_mutex_t is backed by an implementation which
requires that it be constructed (not just zero initialized) then errors
will occur when taking the lock when setting the user data.
Change hb_object_set_user_data to construct the user_data in the created
space and hb_object_fini to call the destructor.

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):

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.

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

[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.

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; }

[aat] Fix unsafe-to-break marking when end-of-text action kicks in
...
The state we are dealing with here is the previous state; so it should
cause unsafe_to_break before current glyph.
I'm surprised this wasn't caught by any tests. Guess we don't have any
fonts with fancy end-of-text forms.

[harfbuzz.cc] Fix OffsetTable name clash with Mac headers
...
There's no easy way to undo a "using namespace" in our sources, so by the time
we get to include hb-coretext.cc from harfbuzz.cc, we already have "using namespace OT"
active, which clashes with Mac headers.
Error was:

[subset] don't set lookup visited in closure_lookups_context_t::recurse.
...
- Lookup::closure_lookups also checks if the lookups visited and sets the lookup to visited. If we set visited in 'recurse' then Lookup::closure_lookups will fail to recurse into the children of the lookup.
- Also when copying ChainRule's skip LookupRecord's that point to lookups which aren't retained. This matches FontTool's behaviour.

Remove unused+wrong UnsizedArrayOf<> operators
...
Said compiler is wrong to err since they are unused. But yeah, they
didn't make sense and were copy/paste leftover.

Drop layout table if layout lookup accelerator allocation failed
...
If the table is kept, when the table is present but only the accelerator
allocation failed, then we run into nullptr dereferences downstream in
hb_ot_map_t::apply when trying to access proxy.accels[i].
To fix this, instead of only setting lookup_count of accelerator_t
itself, drop the whole table to avoid hb-ot-map construction assuming
that the lookups will work correctly despite accelerator allocation
having failed.

meson: use meson.current_source_dir() instead of @CURRENT_SOURCE_DIR@
...
@CURRENT_SOURCE_DIR@ is not listed as a valid string substitution
for custom targets in the Meson reference, and in practice
it does not get substituted when using the vs2019 backend.
