Pre-build numpy wheel for Python 3.15 (no pre-built wheel yet)

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.
