Fix gdb/TUI behavior in response to [Enter] keypress 

gdb/ChangeLog:
2019-03-18  Eli Zaretskii  <eliz@gnu.org>

	* tui/tui-io.c (gdb_wgetch): Don't echo CR.
	(tui_getc): When gdb_wgetch returns a CR, behave the same as when
	it returns a newline.  This fixes a regression in TUI mode, whereby
	the next line is output on the same screen line as the user input.
