tinycrypt: deprecate the library 

Since we now have PSA Crypto APIs/Mbed TLS alternatives for crypto
operations in all Zephyr's codebase we can start the deprecation
of the TinyCrypt libary (as planned from #43712).
This commit is only the inital step: updates documentation and
add the DEPRECATED Kconfig option to the TINYCRYPT one.

=========
* Starting from this release the library is marked as deprecated (:github:`79566`).
The reasons for this are (:github:`43712``):
* the upstream version of this library is unmaintained.
* to reduce the number of crypto libraries available in Zephyr (currently there are
3 different implementations: TinyCrypt, MbedTLS and PSA Crypto APIs).
The PSA Crypto API is now the de-facto standard to perform crypto operations.
