fdo#66762 - Other: com.sun.star.awt.DisplayAccess removed

API_CHANGE:

I removed the undocumented internal API
  "com.sun.star.awt.DisplayAccess"
in commit dde234b6
  "fdo#46808, remove awt::DisplayAccess service."

However, it appears someone was actually using this.

Now, at the same time, we have a method in XToolkit, getWorkArea(),
which looks like it was designed to return this exact information,
but which has been returning zero for as far back as our commit
history goes.

So, to kill two birds with one stone, this commit changes
getWorkArea() to return the information the customer needs, to wit,
the size and position of the primary display.
