feat(tcp_transport): Allow cert bundle attach for wolfssl (IDFGH-16564)

[gojimmypi]

Description

This is the second in a series of pull requests to improve wolfSSL integration with the ESP-IDF as proposed in #16145

As there are multiple changes there, it was suggested that I break the update into smaller pieces.

This PR updates the requirements for wolfSSL in the components/tcp_transport/transport_ssl.c

Testing

The fully-implemented update is on my wolfssl-dev branch. I've been testing with this esp_http_client_example.
