Factor out text measurement from wxDC and wxWindow into wxTextMeasure.

Add a new private wxTextMeasure class implementing methods for measuring text and move the often duplicated (but not always identically) code for doing the same from wxDC and wxWindow into it. Currently this class is only really implemented in wxMSW and wxGTK. Also extend the test for text measuring functions and rename it to MeasuringTextTestCase from MeasuringContextTestCase as it's not wxGC-specific any more. Closes #14705. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@72699 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
