release notes

## What's Changed
- HarfBuzz now the supports the proposed new OpenType “VARC” table. This replaces the previously supported “Variable Composites” experimental feature. “VARC” support is still experimental and it is not enabled unless HarfBuzz is built with experimental APIs enabled:
  https://github.com/harfbuzz/boring-expansion-spec/blob/main/VARC.md
- Autotools build system have been dropped. Meson is the only supported build system in HarfBuzz going forward.
- Speed up “AAT” shaping for short words by up to 4%.
- Ignore unknown “CFF” operators.
- “hb_subset_input_keep_everything()” now keeps also non-unicode “name” table records.
- Update the IANA and OpenType language tag registries.
- Support composite glyphs with very large number of points in hb-draw API.
- Various build fixes.
