harfbuzz: Update to version 8.0.1

- Update from version 7.3.0 to 8.0.1
- Update of rootfile
- Changelog
    Overview of changes leading to 8.0.1
	- 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
	- 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()
