fix: remove CUB_WRAPPED_NAMESPACE and _CCCL_COMPILER_GCC from build flags

Browse Source 
CUB_WRAPPED_NAMESPACE=cccl_preload wraps cub into cccl_preload::cub
but cccl_allocator_preload.cu uses bare cub:: — compilation fails.
_CCCL_COMPILER_GCC=1 conflicts with CCCL auto-detection (redefined warning).

Drop both. CUB_DISABLE_NAMESPACE_MAGIC alone is sufficient.
