The WM API has WM_window_pixels_{x,y,coords}` functions that returns the
window size/point coordinate in the host native pixel size.
As "pixels" in itself doesn't really mean anything the intent of
these functions wasn't really clear. To clarify this, this commit
renames their prefix from `WM_window_pixels_` to
`WM_window_native_pixel_`.
