TPM Revoke Attestation Test

This test runs the TPM Revoke Attestation Test using a test boot driver. This test validates that the TPM driver stack is properly initialized early in the boot process to be usable by early boot components like the Early Launch Anti Malware driver. The test boot driver calls the following function through TBS.sys and validates its results:

TBS_RESULT WINAPI Tbsi_Revoke_Attestation()

This function extends PCR[12] by an unspecified value and increments the boot counter in the TPM to simulate a real world scenario of attestation revocation. The test validates that the PCR 12 and the boot counter values are changed by the Tbsi_Revoke_Attestation API call.
