  Unreviewed build fix for Clang-libstdc++ combo
https://bugs.webkit.org/show_bug.cgi?id=252156

Unreviewed build fix after 260175 at main for Clang and libstdc++ builds.

Assignment of CSSRadialGradientValue::GradientBox variant with a
CSSGradientPosition value is causing compilation failures due to other variant
types that are somehow treated as constructible in this case, due to
CSSGradientPosition being a pair of Ref<CSSValue> values and other variants
having a pair of Ref<CSSPrimitiveValue> values as their first members.

This is avoidable by reconstructing the variant and using the std::in_place_type
helper to explicitly specify that the CSSGradientPosition value should be used
in the variant.
