[SECURITY] NIST / ASCON.

### Is your feature request related to a problem? Please describe.

@acassis noticed this nice article on "Lightweight Cryptography" from NIST [1] mentioning Ascon-Based Lightweight Cryptography Standards for Constrained Devices (NIST Special Publication 800-232 [2]).

It would be nice to have it in NuttX. But its not a trivial implementation, so probably we need to ask if MBED TLS project planning to implement ASCON features? I asked them for planing at https://github.com/Mbed-TLS/mbedtls/issues/10358 :-)

### Describe the solution you'd like

Mbed TLS would be best source for implementation of NIST / ASCON because:
* this will be a world wide standard for embedded systems security.
* MBED TLS is already well established and recognized security-for-embedded project.
* it would be best to have one common single sourced implementation for ASCON from MBED TLS, which also assures proper security review, implementation, validation and updates.
* we already have MBED TLS support in NuttX, as probably other RTOS do, so we could update to have those new features.

### Describe alternatives you've considered

If MBED TLS does not plan to implement the ASCON we need to find alternative source projects, maybe NIST will provide the implementation?
