vTPM/TPM2: Support TPM 2.0 bind and unbind data

Bind data with TPM2_RSA_Encrypt, which performs RSA encryption using
the indicated padding scheme according to PKCS#1v2.1(PKCS#1). If the
scheme of keyHandle is TPM_ALG_NULL, then the caller may use inScheme
to specify the padding scheme.
Unbind data with TPM2_RSA_Decrypt, which performs RSA decryption using
the indicated padding scheme according to PKCS#1v2.1(PKCS#1).
