This patch fixes stdin read hanging on user input when switching tty mode on Windows Fixes #21111 On Windows, when switching from line to raw mode: - Cancel ongoing console read by writing a return keypress to its input buffer. This blocks the main thread until any ongoing read has been cancelled to prevent interference with the screen state. - On the read thread, restore the cursor position to where it was before writing the enter, undoing its effect on the screen state. - Restart reading and notify the main thread.
