* Examples working on Windows and SWTPM
* Check command availability (including for windows blocking it).
* update unseal to work without persistent NV storage
* cleanup cmake from review
* fix a few spelling mistakes
* 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.
When wolfcrypt is not enabled:
* examples/keygen/keyload failed without error message
* examples/seal/seal did not generate an error message
* examples/seal/unseal was missing conditional compiling
Now, this is fixed.
