Reland "desks: Change ChromeVox for mini view (2)"

This is a reland of commit 9b577005c536117a26d7ced5c99b2ee508faafb7

The ChromeVox will read the node name first and then the node value for
the desk name view. Before this CL, the node name and the node value
were all set by the text content in the deskfield. That's why the screen
reader read the desk name view be `Desk 1 Desk 1 edit Text`.

To let it read `Desk name Desk 1 Edit test`, we need to change the node
name to the string `Desk name`, and keep the node value set by the
`GetText`.
However, this change will cause some tast tests failed, thus I uploaded
a CL for fixing the failure in tast test in crrev.com/c/4814306, which
will to compare with the value in the node info instead of the node
name.

> fix, when highlighting the desk name view, it will announce that `Desk 1
> Desk 1 Edit text`, for example. After the fix, it will be `Desk name
