Determine an available PCR bank to be used by a test case by querying the capability TPM2_GET_CAP. The TPM2 returns TPML_PCR_SELECTIONS that contains an array of TPMS_PCR_SELECTIONs indicating available PCR banks and the bitmasks that show which PCRs are enabled in each bank. Collect the data in a dictionary. From the dictionary determine the PCR bank that has the PCRs enabled that the test needs. This avoids test failures with TPM2's that either to not have a SHA-1 bank or whose SHA-1 bank is disabled.
