Chris Waldon 5c54268d40 widget: [API] implement UAX#29 grapheme clustering in text widgets ...

This commit teaches the text widgets how to position their cursor according to
grapheme cluster boundaries rather than rune boundaries. While this is more work,
the results better match the expectations of users. A "grapheme cluster" is a
user-perceived character that may be composed of arbitrarily many runes.

I chose to implement this within widgets for two reasons:

- grapheme cluster boundaries would be extremely difficult to encode within the
glyph stream returned by the text shaper
- not all text needs to be segmented, only text that can be interacted with

All mutation operations exposed by widget.Editor now work in terms of grapheme
clusters instead of runes.
