harfbuzz: update to 8.0.1.

Overview of changes leading to 8.0.1
Wednesday, July 12, 2023
====================================
- Build fix on 32-bit arm.

- More speed optimizations:
  - 60% speedup in retaingids subsetting SourceHanSans-VF.
  - 38% speed up in subsetting (beyond-64k) mega-merged Noto.
  - 16% speed up in retain-gid (used for IFT) subsetting of NotoSansCJKkr.

Overview of changes leading to 8.0.0
Sunday, July 9, 2023
====================================
- New, experimental, WebAssembly (WASM) shaper, that provides greater
  flexibility over OpenType/AAT/Graphite shaping, using WebAssembly embedded
  inside the font file. Currently WASM shaper is disabled by default and needs
  to be enabled at build time. For details, see:

    https://github.com/harfbuzz/harfbuzz/blob/main/docs/wasm-shaper.md

  For example fonts making use of the WASM shaper, see:

    https://github.com/simoncozens/wasm-examples

- Improvements to Experimental features introduced in earlier releases:
  - Support for subsetting beyond-64k and VarComposites fonts.
  - Support for instancing variable fonts with cubic “glyf” table.

- Many big speed optimizations:
  - Up to 89% speedup loading variable fonts for shaping.
  - Up to 88% speedup in small subsets of large (eg. CJK) fonts (both TTF and
    OTF), essential for Incremental Font Transfer (IFT).
  - Over 50% speedup in loading Roboto font for shaping.
  - Up to 40% speed up in loading (sanitizing) complex fonts.
  - 30% speed up in shaping Gulzar font.
  - Over 25% speedup in glyph loading Roboto font.
  - 10% speed up loading glyph shapes in VarComposite Hangul font.
  - hb-hashmap optimizations & hashing improvements.

- New macro HB_ALWAYS_INLINE. HarfBuzz now inlines functions more aggressively,
  which results in some speedup at the expense of bigger code size. To disable
  this feature define the macro to just inline.

- New API:
+HB_CODEPOINT_INVALID
+hb_ot_layout_get_baseline2()
+hb_ot_layout_get_baseline_with_fallback2()
+hb_ot_layout_get_font_extents()
+hb_ot_layout_get_font_extents2()
+hb_subset_input_set_axis_range()

Log message:
harfbuzz, harfbuzz-icu: Update to 6.0.0

Changelog:
  * A new API have been added to pre-process the face and speed up future
    subsetting operations on that face. Provides up to a 95% reduction in
    subsetting times when the same face is subset more than once.

    For more details and benchmarks, see:
    https://github.com/harfbuzz/harfbuzz/blob/main/docs/subset-preprocessing.md

    (Garret Rieger, Behdad Esfahbod)

  * Shaping have been speedup by skipping entire lookups when the buffer
    contents don't intersect with the lookup. Shows up to a 10% speedup in
    shaping some fonts. (Behdad Esfahbod)

  * A new experimental feature, Variable Composites (enabled by passing
    -Dexperimental_api=true to meson), is also featured in this release. This
    technology enables drastic compression of fonts in the Chinese, Japanese,
    Korean, and other writing systems, by reusing the OpenType Font Variations
    technology for encoding ??smart components?? into the font.

    The specification for these extensions to the font format can be found in:
    https://github.com/harfbuzz/boring-expansion-spec/blob/glyf1/glyf1.md

    A test variable font with ~7160 Hangul syllables derived from the
    NotoSerifKR-VF font has been built, with existing OpenType technology, as
    well as with the new Variable Composites (VarComposites) technology. The
    VarComposites font is over 90% smaller than the OpenType version of the
    font!

    Both fonts can be obtained from the ??smarties?? repository:
    https://github.com/behdad/smarties/tree/3.0/fonts/hangul/serif

    When building HarfBuzz with experimental features enabled, you can test the
    ??smarties?? font with a sample character like this:

    $ hb-view butchered-hangul-serif-smarties-variable.ttf -u AE01 \ 
--variations=wght=700

    (Behdad Esfahbod)

  * The HarfBuzz subsetter can now drop axes by pinning them to specific values
    (also referred to as instancing). There are a couple of restrictions
    currently:

      + Only works with TrueType (glyf) based fonts. CFF2 fonts are not yet
        supported.
      + Only supports the case where all axes in a font are pinned.

    (Garret Rieger, Qunxin Liu)

  * Miscellaneous fixes and improvements.

    Rieger, Joel Auterson, Jordan Petridis, Khaled Hosny, Lorenz Wildberg,

    Pramanik)

  * New API
    +hb_subset_input_pin_axis_location()
    +hb_subset_input_pin_axis_to_default()
    +hb_subset_preprocess()
