Update harfbuzz-ng to 0.9.27

Update harfbuzz-ng to 0.9.27

Update the version of harfbuzz to 0.9.27 and set the HAVE_ICU_BUILTIN
define to get it to use the builtin ICU functions.

This also reverts r202083003 as the updated version of harfbuzz-ng
includes that cherry-picked change.

Thanks for updating. What was the conclusion on the failing test cases?

One nit, probably README.chromium should be updated to include the new version
number.
