tpm: add PCR authentication commands support
Add support for the TPM2_PCR_SetAuthPolicy and
TPM2_PCR_SetAuthValue commands.
Change the command file and the help accordingly.
Note: These commands could not be tested because the TPMs available
do not support them, however they could be useful for someone else.
The user is warned by the command help.
