btrace: Remove ui_out cleanups

This patch replaces the cleanups that close the list and tuple of the
btrace instruction history output with ui_out_emit_tuple and
ui_out_emit_list.

This allows removing make_cleanup_ui_out_tuple_begin_end and
make_cleanup_ui_out_list_begin_end.

This patch (along with the previous ones in the series) was regtested on
the buildbot.

gdb/ChangeLog:

	* record-btrace.c (btrace_print_lines): Replace cleanup
	parameter with RAII equivalents.
	(btrace_insn_history): Replace cleanup with RAII equivalents.
	* ui-out.h (make_cleanup_ui_out_list_begin_end,
	make_cleanup_ui_out_tuple_begin_end): Remove.
	* ui-out.c (struct ui_out_end_cleanup_data, do_cleanup_end,
	make_cleanup_ui_out_end, make_cleanup_ui_out_tuple_begin_end,
	make_cleanup_ui_out_list_begin_end): Remove.
