perf parse-events: Improve error location of terms cloned from an event

A PMU event/alias will have a set of format terms that replace it when
an event is parsed. The location of the terms is their position when
parsed for the event/alias either from sysfs or json. This location is
of little use when an event fails to parse as the error will be given
in terms of the location in the string of events parsed not the json
or sysfs string. Fix this by making the cloned terms location that of
the event/alias.

If a cloned term from an event/alias is invalid the bad format is hard
to determine from the error string. Add the name of the bad format
into the error string.
