refactor(windows): redundant icon messages #34274

Browse Source 
Problem:  Two separate window messages are used to get
          the original console icon and set a new
          one on windows, although the `WM_SETICON`
          message returns the original icon itself.

Solution: Replace the two `WM_GETICON` messages with
          two `WM_SETICON` messages, save the return
          values and remove the call to `os_icon_set`.
          Also, replace `os_icon_set` with `os_icon_reset`
          as its only usage is now resetting the
          icon to the original one.
