Bug 2002615 [wpt PR 56127] - Map "shadow-parts" web-feature, a=testonly

Automatic update from web-platform-tests
Map "shadow-parts" web-feature (#56127)

Feature: `shadow-parts`

Reference: https://github.com/web-platform-dx/web-features/blob/main/features/shadow-parts.yml

Notable inclusions

1. Style invalidation tests in `css/selectors/invalidation/` - test that `::part()` selectors properly invalidate when attributes change

Notable exclusions

1. `css/css-view-transitions/` - 7 tests that use `::part()` or shadow parts, but primary focus: View Transitions
2. `css/css-anchor-position/` - 6 tests that mention shadow/tree scopes, but primary focus: CSS Anchor Positioning
3. `scroll-animations/css/` - 3 tests involving shadow trees, but primary focus: Scroll Animations timeline scoping
4. `css/css-animations/` - 3 tests with "shadow-part" in filename, but primary focus: CSS Animations `@keyframes` scoping
5. Other directories with shadow-related tests - Container Queries, CSS Cascade `@scope`, Counter Styles, CSS Mixins, Custom Elements state, and various crash/parsing tests where shadow parts are used as test infrastructure for other features
