SecurityPkg: TPM must go to Idle state on CRB command completion

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3463

In V2: Fixed patch format and uncrustify cleanup

In V1: To follow the TCG CRB protocol specification, on every CRB TPM
 command completion the TPM should return to Idle state, regardless of
the CRB Idle Bypass capability reported by the TPM device.

See: TCG PC Client Device Driver Design Principles for TPM 2.0,
Version 1.0, Rev 0.27
