pkg/harfbuzz: update 8.4 => 11.0 (#6897)

This updates our bundled Harfbuzz from 8.4 to 11.0. The changes from 8
to 11 include a number of correctness and performance improvements.
Packaged releases tend to dynamically link so this won't affect existing
users, but build-from-source users hopefully get an improvement.
