v4.15.1

HIGHLIGHTS:

• created new https://github.com/NVIDIA-RTX/NRD-Sample/tree/simplex branch focusing on the best practices. It offers better performance and has significantly less code than main. This is the recommended branch for diffuse-specular tracing

DETAILS:

• Simplex/PT: focus only on 1rpp tracing with probabilistic split at the primary hit
• Simplex/PT: optimized PSR (always on)
• Simplex/NRD: disabled all compile-time features except anti-firefly
• Main/PT: back-ported improvements from Simplex
• PT: ray tracing buffer and acceleration structure resources bound as root descriptors
• CMake: added Arm64 support, including cross compilation
• CMake: implemented best practices
• NRD updated to v4.15.1
