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

- 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).
