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()
