Changho Hwang d63f9403c0 IB host-no-atomic: GDRCopy + mlx5dv Data Direct for memory-consistent low-latency signaling (#753)
Major enhancements to the IB signal forwarding mechanisms
(`host-no-atomic` mode), primarily adding support for GDRCopy and MLX5
Direct Verbs, and refactoring the signal forwarding path for IB
HostNoAtomic mode. The changes fix memory consistency issues and reduce
signaling latency.
- GDRCopy and MLX5 Direct Verbs MR integration
- Signal forwarding path redesign
- Semaphore and connection API updates
- Environment (`MSCCLPP_FORCE_DISABLE_GDR`) and documentation updates
