Include renderer version into the platform tag in graphics context tests.

This allows to distinguish the results of the same renderer (e.g. GDI+-based
one) on the different OS versions (because GDI+ produces different results
under XP and Windows 8).

Closes #16260.

Add public wxDegToRad() and wxRadToDeg() functions.

Define these functions just once in wx/math.h instead of duplicating them in a
dozen of places.

Add simple font tests for the drawing unit test.

Check that DrawText() results in the expected output.

Currently the tests are disabled for non-Windows systems because of the
problem with the reference file paths there.

See #16261.

Fix querying the value of wxEnumProperty in wxPropertyGridEditor.

Doing this changed the internal state of the control and resulted in the
choice not being updated.

Fix this by using wxPG_PROPERTY_SPECIFIC.

Closes #15449.

Fix recursive self-reference in wxRichTextAttr documentation.
