Replace Device::getDPI() usages in Nebula and Nattable

[ShahzaibIbrahim]

Following are the places that needs to be analyzed and replaced with perhaps getDPIForMonitor

eclipse-nattable/nattable#139 (comment):

NatTable and also some Nebula widgets make use of the API because they do custom paint operations using the GC, and so far the paint operations are pixel based and not automatically scaled. The only way to get the correct sizes for painting is therefore to do the scaling manually. Just as an information when searching for a solution here.

Info: no getDPI() usages in Nebula widgets that we are using at Vector.
