Subject: Metal fix (#6413)

Partially fix #6378

* Fix invalid access mode for texture_buffer

* Fix texture view create issue in metal

In newTextureView, levelRange should represent the mipmap level range,
while sliceRange should represent the texture layer range for texture
array. But the implement inverse those two wrongly.
