Chris Waldon 3406a6da39 deps,font/opentype: update dependencies to fix 32-bit build
This commit updates to a newer version of textlayout
and switches to a fork of the UAX library that builds
properly on 32-bit machines. This should fix 32-bit Gio
compilation for the time being. I hope to switch back
to npillmayer's UAX as soon as he has time to review
the pending pull requests.

Chris Waldon 9576b659d7 text: [API] remove Text and Advances from Layout
These fields are no longer needed with the new text shaper.
Advances is redundant to the glyph information, and Text
should never be used during layout, as you should
traverse the cluster list instead. This commit also removed
the now-unused string field from the path LRU cache key.

Chris Waldon 1e5a3696f5 deps,text,widget,font/opentype: [API] add harfbuzz-powered text shaper
This commit introduces a new text shaping infrastructure
powered by Benoit Kugler's Go source-port of harfbuzz.
This shaper can properly display complex scripts and RTL
text. This commit changes the signature of the text.Shaper
function, which is a breaking API change.

The new functionality is available via opentype.ParseHarfbuzz,
which configures a text.Shaper leveraging the new backend.
