As observed in:

• Add Qwen 2.5 VL mlx-swift-examples#222

Perhaps DType should have finfo() capabilities:

• https://numpy.org/devdocs/reference/generated/numpy.finfo.html
• min, max, etc.

There is inconsistency in the creation methods for MLXArray. Some take dtype: and some take only type: (swift type). Further inconsistencies between free functions (e.g. zeros) and static functions (MLXArray.zeros)
