  [NFC][LoopVectorize] Introduce new getEstimatedRuntimeVF function (#116247)

There are lots of places where we try to estimate the runtime
vectorisation factor based on the getVScaleForTuning TTI hook.
I've added a new getEstimatedRuntimeVF function and taught
several places in the vectoriser to use this new function.
