[Skia] Encapsulate access to PlatformContextSkia's SkCanvas
https://bugs.webkit.org/show_bug.cgi?id=102694

Reviewed by Stephen White.

Source/WebCore:

Add SkCanvas-equivalent methods to PlatformContextSkia, and refactor direct canvas call
sites to use these wrappers instead. This reduces the number of canvas() users from 90+
to 22 (mostly theme/ui code).

No new tests: refactoring only.
