perf(template-outlet): Improved performance

[rkaraivanov]

• Eliminated duplicate cache lookups: _getActionType() now returns both actionType and cachedView, avoiding redundant Map queries in _useCachedView()
• Cached indexOf() results in _moveView(): Store indices instead of calling indexOf() twice for the same view references
• Optimized _recreateView(): Reuse and update existing Map collections instead of creating new Map instances that overwrite existing entries
• Direct detach in _useCachedView(): Use detach(0) directly since directive always inserts at index 0, avoiding unnecessary indexOf() call
• Faster context operations: Use Object.assign() for context updates and spread operator for cloning instead of manual iteration
• Improved _hasContextShapeChanged(): Use Set.difference() with size check fast-path for O(1) lookups instead of O(n) indexOf()
