[RFC]: Move `from_arraybuffer.js` into `@stdlib/ndarray/from-arraybuffer`

### Description

This RFC proposes acting on the `TODO` in `lib/from_arraybuffer.js`, which notes the helper should move to `@stdlib/ndarray/from-arraybuffer`.

The file is dimension-agnostic and is copied verbatim into each dimensional `ctor` package. There are three copies today, in `vector/ctor`, `matrix/ctor`, and `tensor3d/ctor`. Adding `tensor4d` and `tensor5d` would make five.

Separate work on `@stdlib/ndarray/from-arraybuffer` is already under way, which would reclaim all of them at once.

### Questions

Should this land before `tensor4d` starts, so the count stops at three?

### Other

No.

- [x] The issue name begins with `RFC:`.

Start by reading lib/from_arraybuffer.js and its copies in vector/ctor, matrix/ctor, and tensor3d/ctor, then inspect the separate @stdlib/ndarray/from-arraybuffer work already under way. Done means the helper has been moved there and the dimensional packages no longer carry these duplicate copies before tensor4d and tensor5d are added.
