zeertzjq a89b9750ee vim-patch:9.2.0050: WM_SETFOCUS not handled immediately ...

Problem:  In gvim on Windows, a certain problem can occur when the
          WM_SETFOCUS event sent after an external command is not
          processed immediately.
Solution: After posting WM_SETFOCUS, run the message loop to process it
          as quickly as possible (Muraoka Taro).

The problem is that Test_normal11_showcmd may fail when running the
test_normal.vim test.  Investigation revealed that the trigger was an
external command executed in the previous test,
Test_mouse_shape_after_failed_change, when two tests were executed
consecutively.  In gvim on Windows, a WM_SETFOCUS event will be sent
when an external command finishes executing.  This WM_SETFOCUS event is
not processed immediately, but rather by redraw, which is expected to
update showcmd. Because it is queued in typebuf at this time,
clear_showcmd(), which expects typebuf to be empty, cannot update
showcmd.

Also added a test that simulates the above problem.
