Add useful information to Worker.Dump() response

We are currently printing useful system information such as, CPU endianness, libsrtp version, openssl version, openssl CPU info -cpu flags-, io_uring version if enabled, etc. This information is useful regardless of the log level.
Currently this information can only be seen if the log level is DEBUG or WARNING, and an the info tag is enabled. Meaning that in order to see it, one needs to set such log level with the corresponding extra log volume that it brings.
Having such information in Worker.Dump() would allow us to have such system info without generating the unwanted logs.
