Add PS2 keyboard support.
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2316

This patch adds PS2 keyboard support in boot manager, and
add a build flag PS2_KEYBOARD_ENABLE for PS2 keyboard to
build PS2 keyboard driver and SIO driver. Be default the
build flag is not enabled since PS2 keyboard is not common
used. could use -DPS2_KEYBOARD_ENABLE to enable build it
if need this feature.
