vt(4): Adjust the cursor position after changing the window size
A new terminal_set_cursor() is added: it wraps the existing teken_set_cursor() function. In vtbuf_grow(), the cursor position is adjusted at the end of the function. In vt_change_font(), we call terminal_set_cursor() just after terminal_set_winsize_blank(), while the terminal is mute. This fixes a bug where, after loading a kernel video driver which increases the terminal window size, the cursor remains at its old position, in other words, in the middle of the display content. PR: 194421 MFC after: 1 week
