Code Review
This pull request correctly addresses an issue where the text shadow cache was not considering the paint color, leading to incorrect rendering for blurred text with different colors. The fix involves adding the color to the TextShadowCacheKey, updating the corresponding hash and equality functions, and passing the color during key creation. A new unit test has been added which effectively verifies that blurred text with different colors results in distinct cache entries. The changes are logical and well-implemented.

For improved conciseness and to follow modern C++ practices, you can use an initializer list directly within the range-based for loop. This avoids creating a separate named variable for the colors. Using const auto& is also more efficient as it avoids copying the DlColor object in each iteration.
for (const auto& color : {
DlColor::kRed(), DlColor::kGreen(), DlColor::kBlue(), DlColor::kRed(),
}) {| lhs.identifier == rhs.identifier && | ||
| lhs.is_single_glyph == rhs.is_single_glyph && | ||
| lhs.font.IsEqual(rhs.font) && | ||
| lhs.rounded_sigma == rhs.rounded_sigma; |

Now that we have C++20, we should replace this with a defaulted operator==. This would have entirely avoided the issue.
