jiej ac146c4820 [nvFuser] Switching to CudaFusionGuard from BailOut for nvfuser - update 2 (#46452)
Summary:
1. Added CudaFusionGuard as the custom TypeCheck for nvfuser; enabled dynamic shape support with profiling executor;
2. dropped support for legacy fuser;
3. re-enabled nvfuser tests;
4. added registration for profiling record to allow profiling on user specified nodes.
