Subject: [PATCH] Clang/CUDA: Fix language-wide flags when linking .so with
 compiler driver

In commit cfa888a6e2 (Clang/CUDA: Add language-wide flags when linking
with compiler driver, 2024-10-07, v3.31.0-rc1~12^2) we added the wrong
placeholder to `CMAKE_CUDA_CREATE_SHARED_LIBRARY` to represent the
language-wide flags.  The `<FLAGS>` placeholder is for executables.
The `<LANGUAGE_COMPILE_FLAGS>` placeholder is for shared libraries.
The distinction is for historical reasons.

Fixes: #26563
