Removing getDeviceZoom from tests

[arunjose696]

DPIUtil.get[Native]DeviceZoom() is no longer meaningful when monitor-specific scaling is used, so its usage has been removed from most tests. In some cases , these have been left unchanged for now.

Among the occurrences mentioned in Eclipse Platform Issue #195, most have been addressed. Still the following four cases remain unmodified:

1)org.eclipse.swt.tests.junit.Test_org_eclipse_swt_graphics_GC.executeWithNonDefaultDeviceZoom(Runnable)
2)org.eclipse.swt.tests.junit.DPIUtilTests.setup()
3)org.eclipse.swt.tests.junit.Test_org_eclipse_swt_graphics_Image.test_updateWidthHeightAfterDPIChange()

In these three tests, getDeviceZoom() is used to capture the zoom level before execution and restore it afterward. No suitable replacement has been identified yet.

4)org.eclipse.swt.snippets.Snippet373.main(String[])

The snippet description says it is used to to display/refresh Monitor DPI dynamically. However, it uses incorrect DPI access methods and presents a misleading example. It would be better to either remove or rewrite this snippet.
