  -----------
  [mlir] Check for int limits when converting gpu dims (#140747)

When the upper_bound of a gpu dim op (like `gpu.block_dim`) is the
maximum i32 integer value, the op conversion for it causes overflow by
adding 1 to convert the bound from closed to open. This fixes the bug by
clamping the open bound to the maximum i32 value.
