eina-cxx: Added eina_log support for C++, using IOStreams syntax

Summary:
Added eina_log support for C++ using the following macros:

For logging into a domain:

EINA_CXX_DOM_LOG
EINA_CXX_DOM_LOG_CRIT
EINA_CXX_DOM_LOG_ERR
EINA_CXX_DOM_LOG_INFO
EINA_CXX_DOM_LOG_DBG
EINA_CXX_DOM_LOG_WARN

And for logging into the default domain:

EINA_CXX_LOG
EINA_CXX_LOG_CRIT
EINA_CXX_LOG_ERR
EINA_CXX_LOG_INFO
EINA_CXX_LOG_DBG
EINA_CXX_LOG_WARN

The usage is simple as can be seen in the tests:

  efl::eina::log_domain domain("error_domain_name");
  domain.set_level(efl::eina::log_level::critical);
  EINA_CXX_DOM_LOG_CRIT(domain, "something went wrong with the following error: " << error);
