Cleanup: use an array for wmEvent cursor position variables

Use arrays for wmEvent coordinates, this quiets warnings with GCC11.

- `x, y` -> `xy`.
- `prevx, prevy` -> `prev_xy`.
- `prevclickx, prevclicky` -> `prev_click_xy`.

There is still some cleanup such as using `copy_v2_v2_int()`,
this can be done separately.
