7d166fa3 - [flang][cuda] Correct the number of blocks when setting the grid to `*` (#121000)

[flang][cuda] Correct the number of blocks when setting the grid to `*` (#121000) We set the `gridX` argument of `_FortranACUFLaunchKernel` to `-1` when `*` is passed to the grid parameter. We store it in one of `dim3` members. However, `dim3` members are unsigned, so positive-value checks we use later, such as `gridDim.x > 0`, are invalid. This PR utilizes the original gird-size arguments to compute the number of blocks.
