[SPARK-35666][ML] gemv skip array shape checking

[zhengruifeng]

What changes were proposed in this pull request?

In existing impls, it is common case that the vector/matrix need to be sliced/copied just due to shape match.
which makes the logic complex and introduce extra costing of slicing & copying.

Why are the changes needed?

1, avoid slicing and copying due to shape checking;
2, simpify the usages;

Does this PR introduce any user-facing change?

No
