* Fix bug with NV name after first write (only appears when using HMAC session).
* Add new API `wolfTPM2_UnsetAuthSession` to unset auth index for a session and save off the nonce from the TPM. This allows auth to be unset/set again with the same session.
* Cleanup in the NV API's for unsetting of the auth to be handled by caller, not in API.
* Added GPIO configuration logic
* Added more NV attributes per Nuvoton specification
* Fixes from testing on the hardware
* Improvements on tpm2.h definitions
* Fixes after vendor feedback
* Updated the examples README with NPCT75x information and ST33 differences

* Fix for `wolfTPM2_NVCreateAuth` to return `TPM_RC_NV_DEFINED` if already exists (it used to do this, but broke with GPIO changes).
* Fixes for building wolfTPM with wolfCrypt only (no TLS).
* Fix for building without RSA and ECC.
* Fix for `--enable-smallstack` with parameter encryption,
* Fix for nvram/store unused variable.
* Create NV Index for GPIO access right after TPM2_GPIO_Config
* Set and read example to use the NV index created by the config example
* Added instructions about the new gpio examples
* Added vendor check, right now only ST33 supports TPM extra GPIO
* NV Index for GPIO Input requires an extra step, included in gpio/config
* Added sanity check and NV Index delete before new GPIO configuration
* Changes based on peer review
