Fix display updating inside the minibuffer on MS Windows
* src/minibuf.c (read_minibuf): Call `w32_flip_buffers_if_dirty'
after changing the cursor position and redisplaying instead of
`flush_frame'. (bug#55193)
* src/w32term.c (w32_flip_buffers_if_dirty): New function.
* src/w32term.h: Update prototypes.
