Simplify runtime version info string methods
Return a const char* instead of taking a char* as an argument.
This aligns us with the interface used in TF PSA Crypto.

+ * Change the signature of the runtime version information methods that took
+ a char* as an argument to take zero arguments and return a const char*
+ instead. This aligns us with the interface used in TF PSA Crypto 1.0.
+ If you need to support linking against both Mbed TLS 3.x and 4.x, please
+ use the build-time version macros or mbedtls_version_get_number() to
+ determine the correct signature for mbedtls_version_get_string() and
+ mbedtls_version_get_string_full() before calling them.
+ Fixes issue #10308.
