Open grid template row/col inspector menu with right click on title (#6573)

**Problem:**

It should be possible to open the dropdown/context menu for grid
template rows/cols in the inspector by right-clicking the item's title.

**Fix:**

Add an invisible context menu in the title component and trigger it
conditionally by right clicking the title itself.
This solution works better than conditionally opening the same dropdown
menu as the three dots button because it will correctly position it.
