renderer/friend: Improve reversed depth handling and Friend service

Browse source 
This commit makes two significant improvements:

1. Vulkan renderer:
   - Detect and properly handle reversed depth buffers (clear_depth < 0.5)
   - Force depth write enable when needed with reversed depth
   - Use GREATER_OR_EQUAL comparison for reversed depth scenarios
   - Fix transparency issues in games like Civilization 7 by adjusting blend factors
   - Add detailed logging for depth buffer operations

2. Friend service:
   - Implement previously stubbed functions including EnsureFriendListAvailable
     and EnsureBlockedUserListAvailable
   - Add proper event signaling to prevent games from hanging
   - Implement Cancel function for improved compatibility
   - Update copyright notice for the Citron project

These changes improve compatibility with modern games using reversed depth
buffers and prevent hangs in titles that rely on Friend service functionality.
