[mlir][linalg][vector] Refine create{Read|Write}OrMasked{Read|Write} (nfc) (#135350)

The semantics of `createReadOrMaskedRead` and `createWriteOrMaskedWrite`
are currently a bit inconsistent and not fully documented:

* The input vector sizes are passed as `readShape` and
  `inputVectorSizes`, respectively — inconsistent naming.

* Currently, the input vector sizes in `createWriteOrMaskedWrite` are
  not required to be complete: any missing trailing sizes are inferred
  from the destination tensor. This only works when the destination
  tensor is statically shaped.

* Unlike `createReadOrMaskedRead`, the documentation for
  `createWriteOrMaskedWrite` does not specify that write offsets are
  hard-coded to 0.

This PR only updates the documentation and unifies the naming. As such,
it is NFC.

A follow-up PR will generalize and unify the implementation to support,
for example, dynamically shaped destination tensors — a requirement for
enabling scalable vectorization of `linalg.pack` and `linalg.unpack`.
