gsctool: Add option '--any' to auto-detect -s/-t availability.

For partners and developers, it's usually better to have a single simple
instruction to invoke commands. Currently gsctool needs either -s (if
/dev/tpm is not locked) or -t (if trunksd is running) and partners have
to either try both commands (-s or -t) or read the error messages and
try to figure out which option to use.

For example, see the extra logic in CL:831787.

Instead of putting the check everywhere in scripting, it seems easier
and more convenient to have a simple switch - "--any (-a)" that
automatically selects between -s and -t.

BUG=b:70184153
TEST=gsctool -f -a; stop trunksd; gsctool -f -a
