Implement Logging.Create interface
This adds the xyz.openbmc_project.Logging.Create interface on the
/xyz/openbmc_project/logging path. The interface provides a single
method, Create, that allows one to create an event log.
This is an alternative to using the report/commit functions provided by
the phosphor-logging/elog.hpp header file.
Unlike those report/commit interfaces, this does not require that the
entries in the AdditionalData event log property be defined ahead of
time, as the whole AdditionalData contents are just passed in instead of
read out of the journal. This means that the error does not need to
have been defined in the error and metadata YAML files for an event log
to be successfully created. The discussion on if that is still desired
anyway is outside the scope of this commit.
