Fix wxIMAGE_QUALITY_HIGH definition.

Embarrassingly, wxIMAGE_QUALITY_HIGH was never used as it had the same value
as wxIMAGE_QUALITY_BILINEAR due to the changes to these constants in r67203.

After fixing its value in the enum, also change the switch on this enum
elements to avoid g++ warnings about unhandled enum values.

See #12845, #15281.
