security/tpm: Add TPM2 NV_ReadPublic command support

Adds support for `tpm2_nvreadpublic`, which allows to read the public
area and attributes of a TPM2 Non-Volatile (NV) index.

The use case is to check for indices required by Intel TXT to avoid
a reset loop caused by BIOS ACM SCHECK.

TEST=Read Intel TXT TPM2 NV indices in Intel TXT driver.
