perf test attr: Add missing int_mist.uop_dropping event to test-stat files

Setup 'struct perf_event_attr' test was failing on EMR cpu because 'perf
stat' was providing an event that was not included in the test. Type 4
Config 4269 or 10ad, int_misc.uop_dropping.

Add event type=4 config=4269 to test-stat-default and
test-stat-detailed-* files with optional=1 so EMR (Emerald Rapids)
machines can pass the test.
