Align `stroke-dasharray` CSS property parsing with the specification:
- https://svgwg.org/svg2-draft/painting.html#StrokeDashing
- https://svgwg.org/svg2-draft/painting.html#DataTypeDasharray

* LayoutTests/imported/w3c/web-platform-tests/css/css-typed-om/the-stylepropertymap/properties/stroke-dasharray-expected.txt:
* LayoutTests/imported/w3c/web-platform-tests/css/css-typed-om/the-stylepropertymap/properties/stroke-dasharray.html:
Update stroke-dasharray css-typed-on WPT test to match the specification. In
particular, <length> | <percentage> | <number> should be allowed. Negative
values shouldn't be allowed. Also, computed values should be converted to
lengths if numbers were provided.

* LayoutTests/imported/w3c/web-platform-tests/svg/painting/parsing/stroke-dasharray-invalid-expected.txt:
Rebaseline WPT test now that more checks are passing.

* Source/WebCore/css/parser/CSSPropertyParserHelpers.cpp:
Update LengthRawKnownTokenTypeNumberConsumer::consume() to stop ignoring the
UnitlessZeroQuirk parameter. Previously, no matter what value the caller was
passing for this parameter, we were allowing unitless zero. Update call sites
to pass UnitlessZeroQuirk::Allow to maintain pre-existing behavior for now.
However, I made sure to pass UnitlessZeroQuirk::Forbid in
consumeStrokeDasharray() since we want to make sure "0" gets parsed as a
<number>, not a <length> (covered by stroke-dasharray-valid.html WPT test).

(WebCore::CSSPropertyParserHelpers::consumeStrokeDasharray):
Fallback to parsing input as a <number> if parsing it as a <length-percentage>,
as per the specification.

* Source/WebCore/css/typedom/CSSUnitValue.cpp:
(WebCore::isValueOutOfRangeForProperty):
Update isValueOutOfRangeForProperty() to properly indicate that stroke-dasharray
doesn't allow negative values.

* Source/WebCore/style/StyleBuilderConverter.h:
(WebCore::Style::BuilderConverter::convertSVGLengthValue):
(WebCore::Style::BuilderConverter::convertSVGLengthVector):
(WebCore::Style::BuilderConverter::convertStrokeDashArray):
Update our style builder converter to:
- Deal with stroke-dasharray values coming from CSS-Typed-OM, which may not have
  been converted to a CSSValueList yet (unlike values coming from the CSS parser).
- Request that numbers get converted to lengths (by using 'px' unit), now that we
  allow numbers at parser level (per the specification).
