  Add KEY_HOME and KEY_END to the ANSI escape sequence table so that
these keys work in the sandbox SDL console. They generate the escape
sequences ESC [ H and ESC [ F respectively, which are then decoded
by cli_getch.c to move the cursor to the beginning or end of the line.

Also add these keys (plus KEY_DELETE) to the sandbox cros-ec keyboard
matrix so they are recognized by the emulated keyboard controller.

There are no tests for this feature.
