perf trace: Add --bitmask-list command-line option
Introduce a new '--bitmask-list' command-line option for 'perf trace'.
When this option is specified, the formatting of cpumasks is delegated
to bitmap_scnprintf(), enabling cpumasks to be displayed as a condensed,
human-readable list (e.g., "0,2-5,7") instead of the default hexadecimal
representation. An example is provided below:
❯ sudo ./perf trace --show-cpu --bitmask-list --event ipi:ipi_send_cpumask --max-event 5
