Suppress bogus -Wnoexcept from gcc9 in wx/graphics.h

Browse Source 
Due to what looks like a bug, gcc 9.3.0 gives the following incomplete
error message without it:

include/wx/graphics.h:278:7: error: but
‘wxGraphicsGradientStop::wxGraphicsGradientStop(wxGraphicsGradientStop&&)’
does not throw; perhaps it should be declared ‘noexcept’
[-Werror=noexcept]

(without any other diagnostics).
