The current version relies on a Skia quirk where leading moveTos defeat the simple shape detection in SkPath::addPath().

Skia is updating its behavior to make shape detection more robust, and that breaks the assertion EXPECT_FALSE(path.IsOval(nullptr)).

To address, construct an equivalent circle using four conic verbs, which will not be identified as a simple shape. This
preserves all related assertions in the unit test.

This unblocks some Skia shape detection improvements.

Code Review

This pull request updates a unit test to be more robust against upcoming changes in Skia's shape detection. The change from a workaround path creation to an explicit conic-based circle is a good improvement. I've added one suggestion to use a named constant for the conic weight to improve readability and adhere to the C++ style guide.
