Handle some integer overflow run-time errors (#46149, #48979).
This commit (mainly for 32bit CPUs) is the first of a series of
similar commits to handle known integer overflows. Basically, all
of them are harmless, since they affect rendering of glyphs only,
not posing security threats. It is expected that fuzzying will show
up more overflows, to be fixed in due course.
The idea is to mark places where overflows can occur, using macros
that simply cast to unsigned integers, because overflow arithmetic
is well defined in this case. Doing so suppresses run-time errors
of sanitizers without adding computational overhead.

[smooth] Implement minimal dynamic padding for LCD filtering.
Extra bitmap padding for LCD filtering depends on the filter. The
default 5-tap filter needs 2 extra subpixels. The light 3-tap filter
needs only 1 extra subpixel. This space could be already available
due to rounding. In order to optimize the padding, we now expand
CBox for the given filter weights before rounding.
This change breakes current Skia (and Firefox).

[autofit] Make autohint warping NORMAL option.
This moves warping option from LIGHT to NORMAL mode. This makes LIGHT
truly void of hinting in x-direction, with left side bearing never
changed and right side bearing only altered by advance rounding.
Therefore, LIGHT is now ready to return fractional advance. As a
NORMAL option, warping substitutes normal hinting.

* src/autofit/aflatin.c (af_latin_hints_apply): Updated.
* src/autofit/aflatin2.c (af_latin2_hints_apply): Updated.

[truetype] Make `IUP' gvar deltas do the same as Apple (#50832).
When points are not touched by gvar interpolation deltas, FreeType
gave a slightly different result than Apple's CoreText.
The OpenType working group will update the specification to document
the following behaviour: If the two points with deltas to the `left'
and `right' of the untouched point have the same coordinate, then
the inferred delta for the untouched point should be zero.
* src/truetype/ttgxvar.c (tt_delta_interpolate): Implement new
behaviour.

Add new `slight' auto-hinting mode.
This mode uses fractional advance widths and doesn't scale glyphs
horizontally, only applying vertical scaling and hinting.
At the same time, the behaviour of the `light' auto-hinter gets
restored for backwards compatibility: Both vertical and horizontal
scaling is again based on rounded metrics values (this was changed
in a commit from 2017-03-30 as a side effect). To be more precise,
the behaviour is restored for TrueType fonts only; for other font
formats like Type 1, this is a new feature of the `light' hinting
mode.
* include/freetype/freetype.h (FT_LOAD_TARGET_SLIGHT): New macro.
(FT_RENDER_MODE_SLIGHT): New render mode.
* include/freetype/internal/ftobjs.h (FT_Size_InternalRec): Add
`autohint_mode' and `autohint_metrics' fields.
* src/autofit/afcjk.c (af_cjk_hints_init), src/autofit/aflatin.c
(af_latin_hints_init), src/autofit/aflatin2 (af_latin2_hints_init):
Updated.
* src/autofit/afloader.c (af_loader_embolden_glyph_in_slot): Use
`autohint_metrics'.
(af_loader_load_glyph): s/internal/slot_internal/.
Initialize `autohint_metrics' and `autohint_mode' depending on
current auto-hint mode.
Use `autohint_metrics'.
Updated.
* src/base/ftadvanc.c (LOAD_ADVANCE_FAST_CHECK): Updated.
* src/base/ftobjs.c (FT_Load_Glyph): Updated.
(FT_New_Size): Allocate `internal' object.
* src/pshinter/pshalgo.c (ps_hints_apply): Updated.
