  [Skia] Return early when receiving an all-zero DashArray
https://bugs.webkit.org/show_bug.cgi?id=285610

Reviewed by Carlos Garcia Campos.

Validate dash array elements according to the spec, including
optimising the all-zero case. An all-zero DashArray can be detected and skipped.

* Source/WebCore/platform/graphics/skia/GraphicsContextSkia.cpp:
(WebCore::isValidDashArray): New helper that checks array is valid.
(WebCore::GraphicsContextSkia::setLineDash): Use the helper to assign a
nullptr and return early.
