Add initial CUDA 13.0 support for pulsar and pycuda modules

Summary:
CUDA 13.0 introduced breaking changes that cause build failures in pytorch3d:

**1. Symbol Visibility Changes (pulsar)**
- NVCC now forces `__global__` functions to have hidden ELF visibility by default
- `__global__` function template stubs now have internal linkage

**Fix:** Added NVCC flags (`--device-entity-has-hidden-visibility=false` and `-static-global-template-stub=false`) for fbcode builds with CUDA 13.0+.

**2. cuCtxCreate API Change (pycuda)**
- CUDA 13.0 changed `cuCtxCreate` from 3 to 4 arguments
- pycuda 2022.2 (current default) uses the old signature and fails to compile
- pycuda 2025.1.2 (D83501913) includes the CUDA 13.0 fix

**Fix:** Added CUDA 13.0 constraint to pycuda alias to auto-select pycuda 2025.1.2.

**NCCL Compatibility Note:**
- Current stable NCCL (2.25) is NOT compatible with CUDA 13.0 (`cudaTypedefs.h` removed)
- NCCL 2.27+ works with CUDA 13.0 and will become stable in early January 2026 (per HPC Comms team)
- Until then, CUDA 13.0 builds require `-c hpc_comms.use_nccl=2.27`
