+perf(BaseStyles): Remove expensive :has([data-color-mode]) selectors

+perf(Dialog): Add feature flag for CSS :has() selector performance optimization
+
+- Add `primer_react_css_has_selector_perf` feature flag (default: false)
+- When flag is OFF: uses legacy `body:has(.Dialog.DisableScroll)` selector
+- When flag is ON: uses optimized direct `body[data-dialog-scroll-disabled]` data attribute with ref counting
+- Enables gradual rollout and easy rollback of performance optimization

+perf(hasInteractiveNodes): Optimize with combined selector and early attribute checks
+
+- Use combined querySelectorAll selector instead of recursive traversal
+- Check attribute-based states (disabled, hidden, inert) before getComputedStyle
+- Only call getComputedStyle when CSS-based visibility check is needed
