Steps to reproduce

Steps:

1. Open this link to live example: https://stackblitz.com/edit/qsyrrzxn?file=src%2FDemo.tsx
2. Try to drag a row over any cell other than row reorder cell (with reorder icon)
3. Notice dropping doesn't reorder the row

Current behavior

It is not possible to perform row reorder by dropping on a cell which has cell reorder disabled.

Expected behavior

It should be possible to reorder anywhere in the Data Grid

Context

Discovered while working on #18251

Here's the culprit:

We have to introduce some kind of state which gets set on rowDragStart and gets cleared on rowDragEnd.
