Why is m_tlsConnectionInfo needed? What's the problem if setting to networkLoadMetrics.tlsProtocol directly?

I think it'd better to use struct and WTF_MAKE_STRUCT_FAST_ALLOCATED.

You shouldn't use 'get' for these functions (Bug 227766). However, OpenSSLHelper.cpp has more 'get'. Sooner or later, they should be renamed.

A CurlRequest gets metrics in CurlRequest::didReceiveHeader and CurlRequest::didCompleteTransfer but in didCompleteTransfer, curl_easy_getinfo can't obtain SSL pointer.
This is because when the connection ends, libcurl clears ssl context in the curl handle internally.
Therefore, we should keep TLS information in m_tlsConnectionInfo when didReceiveHeader is called.

Removed 'get' from function names.
