Fix: IME conversion candidate window not correctly placed on macOS

Blender needs to tell the input method program where the conversion
candidate window is during Japanese and Chinese input.

In macOS, there are displays where the window size and the native pixel size
are different, so the candidate window may appear in an unnatural position.

This patch converts the cursor position x and y for matching macOS window
coordinate. On Windows, GHOST_GetNativePixelSize returns 1, so it has no effect.
