[PATCH v4 1/2] windowscodecs: Use IWICImagingFactory_CreatePalette in write_source.

[Rémi Bernon]

Instead of PaletteImpl_Create.

Signed-off-by: Rémi Bernon

v4: As an alternative to v3, with unix_lib.c copied to wmphoto instead,
    as it seems to be preferred it over the #ifdef. I don't mind either.
