Set minimum HarfBuzz version back to 2.0.0.

Browse source 
Due to the new GSUB parsing we no longer need
`hb_ot_layout_lookup_get_glyph_alternates`.

This partially reverts commit 5d2fd7608a.

* CMakeLists.txt (HARFBUZZ_MIN_VERSION), meson.build (harfbuzz_dep),
  builds/unix/configure.raw (harfbuzz_pkg): Set version to 2.0.0.

* src/autofit/ft-hb-decls.h: Remove entry for
  `hb_ot_layout_lookup_get_glyph_alternates`.

A side effect of this change is that FreeType no longer uses
HarfBuzz header files (if HarfBuzz support is activated). To make
this work, we now require at least HarfBuzz version 2.6.8,
released in June 2020.
