Add wxUxThemeHandle::DrawBackground() wrapper and use it

Browse source 
This is sightly shorter/more convenient to use than providing all the
parameters to ::DrawThemeBackground() every time.

Similarly to ca5f244f15 (Add wxUxThemeHandle::GetColour() replacing
MSWGetThemeColour(), 2022-12-09), this is just a refactoring which
shouldn't result in any changes in behaviour.
