perf pmu-events: Don't lower case MetricExpr
This patch changes MetricExpr to be written out in the same case. This
enables events in metrics to use modifiers like 'G' which currently
yield parse errors when made lower case. To keep tests passing the
literal #smt_on is compared in a non-case sensitive way - #SMT_on is
present in at least SkylakeX metrics.
