[Infra][Numpy2] Use np.asarray in both np1 and np2 (#65947)

SigureMo · web-flow · commit 35d7e1a21120 · 2024-07-15T10:51:38.000+08:00
* [Infra][Numpy2] Use `np.asarray` directly * rename ut * replace all np.array with np.asarray * Revert "replace all np.array with np.asarray" This reverts commit f712a8d. * disable failed case * rename back * fix test_transform_static
