Improvements and known bug fixes

• NVEXT: more nvapi stubs implemented by @aquadran
• airconv: shader's fast-math behavior is changed a lot in this version, and it is still not the final version (more trade-offs between performance and correctness). Possible side effects (if any, likely good ones) you may get: 1. better or lower performance 2. rendering looks more correct or broken than before. Please do report if you see a regression. We aim to make this more customizable in the future.
• Street Fighter V: fixed wrong tone-mapping due to an unintended clear of stencil buffer.
• Epic Online Services: fixed crashing of any game launched from Epic.
• Umamusume: Pretty Derby: fixed background video not playing in login screen.
• Counter-Strike 2: fixed blank screen when both exclusive fullscreen and MSAA are both enabled.
• Warframe: fixed DLSS not detected by game.
• Alien: Isolation: fixed vertex explosion.
• Stellaris: fixed missing artworks due to missing handling of BGRX8 format, where X component should be read as 1.0.
• Ori and the Will of the Wisps: fixed missing character due to an edge case of current stream output implementation.
• World of Tanks: fixed z-fighting on specific models.
• Deadlock: fixed corrupted MTLFX temporal scaler output.
