Topdown metrics are missed in the default perf stat on the hybrid machine,
add Topdown metrics in default perf stat for hybrid systems.

Currently, we support the perf metrics Topdown for the p-core PMU in the
perf stat default, the perf metrics Topdown support for e-core PMU will be
implemented later separately. Refactor the code adds two x86 specific
functions. Widen the size of the event name column by 7 chars, so that all
metrics after the "#" become aligned again.

The perf metrics topdown feature is supported on the cpu_core of ADL. The
dedicated perf metrics counter and the fixed counter 3 are used for the
topdown events. Adding the topdown metrics doesn't trigger multiplexing.
