pixmap: make PixmapDirtyCopyArea public

Browse Source 
PixmapDirtyCopyArea() is about to be used outside of pixmap.c, so fix up
its interface by specifying the dirty area directly rather than passing a
`PixmapDirtyUpdatePtr`. This makes it easier to use outside of pixmap.c, as
the caller doesn't need to create a bulky PixmapDirtyUpdateRec to use this
function.
