patch 9.2.0215: MS-Windows: several tests fail in the Windows CUI.

Browse Source 
Problem:  The Windows CUI actively buffers transmissions to terms. Patch
          0200 changed the timing of DECRQM transmissions, and
          out_flush() is no longer called after transmission. Therefore,
          actual term initialization does not occur until the buffer is
          flushed, causing the following tests to fail:
            - test_autocmd.vim - Test_Changed_FirstTime()
            - test_mapping.vim - Test_error_in_map_expr()
            - test_messages.vim - Test_mode_message_at_leaving_insert_with_esc_mapped()
            - test_search.vim - Test_search_cmdline_incsearch_highlight_attr()

            The failures since version 200 can be confirmed in the following CI jobs.
            - 9.2.0200 https://github.com/vim/vim/actions/runs/23312934497
                - https://github.com/vim/vim/actions/runs/23312934497/job/67804736843

            - 9.2.0199 https://github.com/vim/vim/actions/runs/23311871938
                - The above test can be confirmed to be successful.
Solution: After sending DECRQM in send_decrqm_modes(), explicitly call
          out_flush() to ensure terminal initialization (Muraoka Taro).
