Roll Skia from 62095415d5e2 to ab9b798555a6 (20 revisions) - #195339

CanvasKit's ParagraphStyle gained softHyphenString in Skia 1bd2b0627c,
which rolled into Flutter in flutter#195339. CkParagraphStyle now sets it from
ParagraphStyle.hyphenCharacter, so the hyphenCharacter test runs on
CanvasKit too.

Part of flutter#189617.

Part of flutter#189617.

Adds `hyphenCharacter` to `dart:ui`'s `ParagraphStyle`, so apps can
choose the string drawn at the end of a line that breaks at a soft
hyphen (U+00AD) instead of always "-". If it is null, "-" is drawn as
before. The empty string draws nothing, and the line still breaks there.

The engine passes it to Skia's `ParagraphStyle::setSoftHyphenString`,
which already reserves the string's width when breaking lines and
includes it in selection boxes. Skwasm gets a
`paragraphStyle_setSoftHyphenString` binding for the same call, and
CanvasKit sets the `softHyphenString` property that rolled in with
flutter#195339.

This is the additive `dart:ui` part of flutter#189617. The name and shape
follow the API question there, and I am happy to change them. The
framework side (`TextStyle.getParagraphStyle`, `TextPainter`,
`RenderParagraph`, `RichText` and `Text`) is ready as a follow-up PR,
along with a breaking change page for flutter/website, since a new
`getParagraphStyle` parameter breaks classes that override it. I will
open both once this lands.

WebParagraph stores the value but does not draw soft hyphens yet.
flutter#195366 adds soft hyphens there for flutter#193506, and can use this value once
both land.
