Fix is_address_from verifier error on CUDA below 13.1

[PointKernel]

Description

This PR fixes a CUDA 12.9 + GCC 10 CI failure uncovered by #10688, which added cuda::barrier/memcpy_async to the fixed_capacity_map ref and with them a cuda::device::is_address_from(ptr, shared) check. On CTK 12.9 + GCC 10, is_address_from(ptr, shared) lowers ::__isShared to @llvm.nvvm.isspacep.shared with the caller's typed pointer instead of i8*, so the LLVM verifier aborts.

The local case already works around this at < 13.1. The global/constant/shared/cluster_shared cases were left at < 12.3. Fix: bump those four to < 13.1 so they use the inline-PTX isspacep path below 13.1, matching local.

1. libcu++ address-space fallback triggers NVVM register-width failure · 21 jobs

Explanation: The PR expands the inline-PTX address-space fallback from CUDA versions below 12.3 to versions below 13.1. Every CUDA 12.9/13.0 configuration then fails memcpy_async and pipeline compilation with an NVVM register-width diagnostic, sometimes followed by a compiler crash, indicating that an `isspacep` asm operand is reaching NVVM with a width incompatible with its `"l"` constraint.

- (16 additional affected jobs omitted from this prompt)

Verify the regression by narrowly precompiling `cuda/memcpy_async/memcpy_async_32.pass.cpp` with nvcc 12.9 or 13.0, then inspect `libcudacxx/include/cuda/__memory/address_space.h`. The likely correction is to materialize `__ptr` as a guaranteed 64-bit generic address, such as an appropriately validated `cuda::std::uintptr_t`, before passing it to the `"l"` operand in every fallback `isspacep` block; preferably centralize this in a small helper to avoid inconsistent cases. Confirm that the conversion preserves PTX generic-address semantics, implement the fix, add or adjust focused coverage for global/shared pointers, and run targeted lit precompile validation for `cuda/memcpy_async/memcpy_async_32.pass.cpp` and one `cuda/pipeline/pipeline_memcpy_async_*` test under CUDA 12.9 and 13.0, plus a CUDA 13.3 sanity compile.

2. cuML device_scalar initialization calls deleted rvalue constructor · 1 job

Explanation: RMM 26.10 deletes construction of `device_scalar` from a temporary value, while cuML initializes several scalars directly from literals such as `0`, `1.0`, and `0.0`. Overload resolution therefore selects the deleted rvalue overload in the UMAP and solver sources.

Reproduce the cuML portion of the RAPIDS smoke build at the recorded dependency revisions and inspect the deleted constructor contract in `rmm/device_scalar.hpp`. If rejection of temporary host values is intentional, update all affected cuML call sites, including `src/umap/simpl_set_embed/algo.cuh` and `src/solver/cd.cuh`, to use correctly typed named lvalue initializers whose lifetime satisfies RMM's asynchronous-copy requirements; do not restore an unsafe rvalue overload merely to compile. If the dependency revisions are incompatible instead, align the RMM and cuML refs. Run focused compilation of the UMAP parametrizable test, the UMAP object, and the solver object, then rerun the cuML RAPIDS smoke target.

3. cuGraph device_scalar initialization calls deleted rvalue constructor · 1 job

Explanation: cuGraph repeatedly constructs RMM device scalars from temporary `size_t{0}` values, but RMM 26.10 explicitly deletes the corresponding rvalue constructor. The same incompatibility appears across many instantiations of `edge_partition_device_view.cuh` and related cuGraph primitives.

Compile the failing `cugraph_common` sampling object first, search for all remaining temporary-value constructions, and rerun the focused cuGraph smoke build.

4. CUDA 13.3 ptxas memory allocation failure · 4 jobs

Explanation: Four CUDA 13.3 Windows jobs fail in varying atomics tests because ptxas cannot allocate memory, without a source-level compiler diagnostic. The varying test sets and common assembler message indicate runner resource exhaustion or excessive concurrent assembly rather than the address-space code regression.

Verify this as an infrastructure/resource failure by rerunning one failed atomics lit compile on a clean CUDA 13.3 Windows runner while monitoring available memory and reducing build or lit parallelism. If the focused compile passes, adjust the job's concurrency, runner memory allocation, architecture fan-out, or retry policy rather than changing library code; if it still fails at low concurrency, preserve the exact nvcc invocation and reduce it to a compiler reproducer. Then rerun the affected CUDA 13.3 C++17 and C++20 libcu++ build configurations.
