Add the getAssociationEndPoints method

There are currently many files that use the get endpoints methods[1].
Since they are general methods, they are defined in the
dbus_utility.hpp file and will be further refactored in subsequent
patches.

Since the current endpoints of phosphor-objmgr do not support
object_path and fails in romulus CI[2], so we should revert to
std::string.

Also, Updated the populateSoftwareInformation method of sw_utils.hpp

[2] https://gerrit.openbmc.org/c/openbmc/bmcweb/+/58924/22/include/dbus_utility.hpp#98

When an object with, for example, an object path of pathA uses
the following values:

["foo", "bar", "pathB"]

The mapper will create 2 new objects:

pathA/foo
pathB/bar
