Backport of NVIDIA#2108 to the 12.9.x branch so that cuda-bindings 12.9.x wheels are available for Python 3.15, which the main branch needs in order to build cuda-core. - Add 3.15 / 3.15t to the build matrix - Upgrade cibuildwheel to v4.0.0rc1 (required for cpython-prerelease) - Enable cpython-prerelease in CIBW_ENABLE - Add amd64-only test entries for 3.15 / 3.15t (CUDA 12.9.1)

- Remove 3.13t from build matrix and all test matrices (already dropped on main). - Work around Meson finding GNU link.exe (from Git for Windows) instead of MSVC link.exe when building numpy from source for pre-release Python on Windows.

There was a problem hiding this comment.
Note: Adding this workaround because it choked Meson:
..\meson.build:1:0: ERROR: Found GNU link.exe instead of MSVC link.exe in C:\Program Files\Git\usr\bin\link.EXE.
This link.exe is not a linker.
You may need to reorder entries to your %PATH% variable to resolve this.

- Add arm64 entries for 3.15 / 3.15t (linux pull-request) - Add Windows pull-request entries for 3.10, 3.11, 3.14, 3.14t, 3.15, 3.15t to keep in sync with main

NumPy does not ship pre-built wheels for Python 3.15 yet. Build the wheel from source during the build stage (where compilers are available), upload it as an artifact, and download/install it in the test stage before running cuda.bindings tests.
