Move tui_dispatch_ctrl_char to tui-io.c

tui_dispatch_ctrl_char is only called from a single spot in tui-io.c,
so move the function to that file and make it static.

gdb/ChangeLog
2019-07-17  Tom Tromey  <tom@tromey.com>

	* tui/tui-io.c (tui_dispatch_ctrl_char): Move from tui-command.c.
	Now static.
	* tui/tui-command.h (tui_dispatch_ctrl_char): Don't declare.
	* tui/tui-command.c (tui_dispatch_ctrl_char): Move to tui-io.c.
