  [NVPTX] restrict `cvta.param` use to kernels only. (#112278)

If `cvta.param` is used in regular functions, it may produce an
invalid pointer. It's unclear if it's a bug in ptxas or we're not using `cvta.param` correctly, but,
regardless of the underlying reason, the instruction has to be disabled for non-kernels, at least for now.
