gsctool: add options to control ccd

The user needs to be able to unlock/open/lock CCD in addition to
setting the CCD password.

This patch adds command line options for these three CCD subcommands.
They all are communicated to the TPM using the same vendor command.
'open' and 'unlock' subcommands could require the user to enter the
password. This is indicated by the appropriate vendor command return
code.

If return code of 'open' or 'unlock' subcommand indicates the need for
physical presence, the utility starts polling the Cr50 prompting the
user to press the power button when the chip expects it.

Some input parameters sanity checks are added to make sure that the
user does not request mutually exclusive actions.

BRANCH=none
BUG=b:62537474
TEST=verified that CCD can be unlocked and opend with and without
     password, with and without PP required.
