Update harfbuzz-ng to 1a5a91dc0d8bf4b72a2f22dc6300b06ad7000b79.

Update harfbuzz-ng to 1a5a91dc0d8bf4b72a2f22dc6300b06ad7000b79.

Preparing for using HarfBuzz-ng as a secondary text shaper on mac.
CoreText doesn't support OpenType features so we need additional
text shaper to support -webkit-font-feature-settings property.

I don't think this version is ready for transition on Linux because I
could see considerable performance regressions when I run cycler tests.

BUG=68551
TEST=None. This CL doesn't change build process for now.

I'd like to update harfbuzz-ng to use it as a secondary text shaper on mac to
support -webkit-font-feature-settings property.
https://bugs.webkit.org/show_bug.cgi?id=69826 is the WebKit bug entry. An WIP
patch will be uploaded there soon.
