[toge]

Specify library name and version: wolfssl/*

I met compilation errors on executing conan install --requires=libcurl/8.5.0@ --build=missing -o libcurl/\*:with_ssl=wolfssl.

To solve it, I have to build wolfssl with --enable-curl arg which has been introduced since 5.2.0.
https://www.wolfssl.com/using-curl-with-wolfssl-and-tls-1-3/

This PR is adding the option to set --enable-curl.
