CONFIG_JWT_SIGN_RSA_LEGACY was already deprecated, but we agreed on
removing all usages of legacy Mbed TLS crypto from Zephyr codebase quickly
in order to prepare for the transition to Mbed TLS 4.0/TF-PSA-Crypto 1.0.
Therefore this commit remvoes support for CONFIG_JWT_SIGN_RSA_LEGACY
before the deprecation period expires.
