Move grub_getkeystatushelper() function from grub-core/commands/keystatus.c
to grub-core/kern/term.c and export it so that it can be used outside of
the keystatus command code too.
There's no logic change in this patch. The function definition is moved so
it can be called from grub-core/kern/term.c in a subsequent patch. It will
be used to determine if a SHIFT key has was held down and use that also to
interrupt the countdown, without the need to press a key at the right time.
