Chris Waldon 90e57c2b18 widget: add method to acquire label shaping metadata ...

There are many times when an application wants to know metadata about shaped text without
allocating a stateful text widget such as widget.Selectable. This commit introduces widget.TextInfo
and adds an extra LayoutDetailed method to widget.Label returning this struct. Currently
the struct only provides the information necessary to determine whether the text was truncated
(useful for deciding whether a tooltip makes sense), but it can be expanded to include text metrics
in the future for applications which require those.

In the future other text widgets may surface methods of acquiring widget.TextInfos, but the critical
gap in the API is that we can't currently determine whether a stateless label was truncated, so
I'm starting here.

I considered making Label.Layout() always return this, but I didn't want to introduce a breaking
API change yet. I have some other thoughts I want to explore about the label API which might
trigger breaking changes (moving parameters into fields).
